The research question

Complaint volume is the headline number on every collector profile, but volume alone conflates size with conduct: a national bureau handling tens of millions of accounts will always log more complaints than a regional agency, even if it resolves them better. A fairer lens on conduct is what happens after a consumer files. The CFPB records two response signals for every complaint: whether the company answered within the federally mandated window, and whether the consumer disputed the company's response afterward. This analysis ranks the 521 collectors with at least 200 CFPB complaints on those two signals — the operators that most often leave consumers dissatisfied, and the operators slowest to respond at all.

Collectors consumers most often dispute after a response

The chart below ranks collectors by the share of complaint responses that consumers marked as unsatisfactory. Across the 521 collectors in this base, the average dispute rate is 18.4%. The collectors at the top of this list resolve complaints to the consumer's satisfaction far less often than their peers — a signal that survives the size adjustment because it is a rate, not a raw count.

Why the dispute rate matters

A high dispute rate means consumers frequently believe the company's answer did not address the underlying problem. Under the CFPB process a company can close a complaint with an "explanation" that satisfies the regulator's procedural requirement while still leaving the consumer convinced the debt is wrong, already paid, or not theirs. A persistently high dispute rate, especially paired with a top complaint category like "attempts to collect debt not owed", is one of the clearest available proxies for the verification and accuracy problems the FDCPA was written to curb. It does not prove wrongdoing — disputes are consumer perceptions — but it isolates the resolution-quality dimension that raw volume hides.

Collectors slowest to respond within the federal window

The second chart ranks the same base by timely-response rate, lowest first. The CFPB requires companies to respond to most complaints within 15 days (60 days for credit-reporting matters). The fleet-wide average timely-response rate is 94.3%, so almost every established collector clears the bar; the value of this ranking is in surfacing the rare operators that do not. A low timely-response rate is an operational red flag independent of the underlying dispute: it means consumers wait longer for any answer, and it often correlates with thinner complaint-handling staffing.

How to use these rankings

If a collector on either list is contacting you, treat its profile as a starting point for documentation, not a verdict. Request written validation of the debt within 30 days of first contact, keep every letter and call log, and file your own CFPB complaint if the company cannot substantiate the debt — your complaint becomes part of the same public dataset that powers this analysis. A collector with both a high dispute rate and a falling complaint trend may be improving; one with a high dispute rate and a rising trend warrants more caution. Always read the per-issue breakdown on the collector's profile to see whether your experience matches the documented pattern.

The regulatory backdrop

The two signals in this analysis sit at the center of the modern debt-collection rulebook. The CFPB's Regulation F, which took full effect in November 2021, tightened both the cadence of permissible contact and the content of the validation notice a collector must send before pressing a debt. A collector that posts a high dispute rate after Regulation F has fewer excuses than one whose record predates it: the validation-notice requirements were designed precisely to head off the "is this debt even mine" disputes that dominate the complaint mix. When you read a collector at the top of the dispute-rate chart, it is worth checking whether its complaint trend is rising or falling — a falling trend after 2021 may indicate the company has adapted its notices, while a flat or rising trend suggests the resolution problem is structural rather than transitional.

It is also worth separating the two failure modes. A low timely-response rate is an operational problem: the company is not staffed or organized to answer within the federal window, and that is visible to the regulator on every single complaint. A high dispute rate is a substantive problem: the company answers on time but the answer does not satisfy the consumer, which points to the underlying accuracy of the debt or the adequacy of the documentation rather than the speed of the reply. A collector that scores poorly on both is the clearest candidate for a written validation demand and, if it cannot substantiate the debt, a CFPB complaint of your own. A collector that is slow but rarely disputed, or fast but frequently disputed, tells you which lever to pull first.

Methodology and limitations

Every figure on this page is rendered at request time from a live query against the PlainCollector database, a normalized copy of the CFPB Consumer Complaint Database (debt-collection product). The base is restricted to collectors with at least 200 total complaints so that response rates are computed on a stable sample rather than a handful of cases. Dispute and timely-response percentages are the CFPB-published rates for each company. The data covers 2013 through early 2026. Two caveats apply: response rates describe how a company handles complaints once filed, which is separable from how many complaints it generates; and a complaint is a consumer report, not an adjudicated finding of misconduct.
