Never able to make returns at H-E-B using my card

Am I Trippin or is there some sort of scam going on if we have the card that we paid with? We should be able to make returns using the card and sometimes I don’t have the receipt as it’s a lot of stuff to keep up with but for well over a year now, I’ve been trying to make returns at H-E-B using my card And none are available. We’ve had to use our licenses multiple times because it says that there is no purchase made on the card, which is not accurate at all. One employee said that it may be because we use tap to pay, but I don’t think that’s right because we have also used swipe or chip since being told this and it’s still happening. What is the issue? What is the process? Why is this at multiple H-E-B locations?
