Complaint Resolution Index (CRI)

Complaint Resolution Index (CRI) Explained The Complaint Resolution Index (CRI) is an indicator on how responsive a company is in addressing and resolving customer complaints brought to their attention by BCA. If they are considering doing business with the company, consumers can use this indicator to forecast the likelihood of having their issues addressed if a problem arises. CRI measures the company's customer satisfaction abilities through BCA’s complaint mediation process.

A variety of factors are considered when calculating CRI. This includes how quickly a company responds to complaints, the number of complaints against a company, whether the company addressed complaint allegations, and the outcome of the complaints. CRI is just a subset of the overall rating for the company. Consumers are encouraged to take into consideration the company's CRI, their overall BCA letter rating and other relevant information about the company so they can make a well-informed purchasing decision.

Customer Complaint

3/13/2026

I received a non-compliance violation without proper notice. On October 3, 2025, it came to my attention that my merchant account was charged a $5000 Visa non-compliance fee on September 19, 2025. When I contacted Fiserv, they informed me they received notification of the violation on September 2, 2025, and attempted to reach me by phone on September 16,17,18 from an unidentified phone number. They failed to send me the required 30-day written notice of the violation including details of the infraction, corrective measures, and potential penalties. They maintain this was a fine, not a fee, and therefore the 30-day notice rule doesn't apply, and I have no other options. And they state Visa would have the right to charge a further fine in the same amount should the appeal fail. I submitted three written requests for a Visa Compliance Review. The acquirer refused and ignored all requests This refusal denies my right to due process under Visa's mandated framework. The acquirer is obstructing required escalation procedures. They sent a copy of the customers card attestation receipt, which was dated April 30, 2025, six months prior to when the fee/fine was imposed. Resolution Sought Submit the Visa Compliance Review letter Reimburse monies for failure of required 30-day written notification

Dear Ms. Rentz, We continue to stand by what we provided in the CFPB complaint 251028-25362285. This was a fine and as such is your responsibility. Fiserv has address this issue but in writing two other times, and over the phone. We consider this matter closed. Fiserv

This company is unethical and beware merchants! They state that when they receive a notice of a non-compliance violation fee/fine from Visa that they are not required to give merchants a 30-day written notice informing them of the violation and giving the merchant ample time to respond to Visa and dispute the violation. They claim that a couple of phone calls from an unknown number is ample notice before they debit your account, in this case $5000. And when I requested that a letter of dispute be presented to Visa they refused. Stating the possibility of being charged an additional fee/fine if Visa sees fit. They have continuality and repeatedly violated Visa's core rules and regulations. I would like to see where Visa states that an acquiring bank is NOT required to give merchants a 30-day written notice. In, closing I wish I had read the reviews before signing with them. It appears they are notorious for holding and taking merchants' monies without notice or viable reasons.
