Trying to get a Credit Line Increase but having same issue.

I currently have a $1K credit limit Quicksilver Card and have had it for well over a year.

I’ve been trying to get a credit line increase, but anytime I do, I get the document from Cap1 stating: “unable to obtain your most recent monthly payment data from the credit reporting agency.” This is the only thing that’s listed.

I called Cap1 and they said that I need to contact the credit reporting agency listed on the document, which is Equifax.

I contacted Equifax and they understood and did a dispute.

A month later I tried again…same message. I have tried for the past 4 months.

I pay my balance off immediately after large purchases and don’t have a balance on my monthly statements - could this be the problem?

Any advice would help.
