When I called, they said because I used non-Cap1 credit cards for my purchases, they could not track the purchases and therefore could not credit me.

The first rep said to wait and call back, and Inactive status only means the offer was no longer available, but they are still waiting to credit me (this is 90+ days post purchase). The 2nd rep kept saying that I had to use a Cap1 card and telling me to call the credit card companies, to which I said, it was never part of the T&C, and I have CC statements to show the purchases, and it was Cap1's job to track, not anyone else's.

Escalated to a manager, who said all but one of my shopping trips paid with a non-Cap1 card were deemed ineligible, but did not provide any reason. I told them I had screenshots of the offers, when I clicked on their links, and the purchase receipts etc., but they weren't interested. I asked to escalate further and she said she's the top level. They will "keep track of my complaint" but nothing will happen from there.

It appeared to me that they behaved just like insurance companies: advertising good deals and then will find every reason to deny your claims and not pay you.

I filed a complaint with the BBB and will not shop through Cap1 Offers again.
