AP is accusing me of “using customer coupons”

I’m an extreme coupon-er and I’m always using as many coupons as I can for the items I have. All of my coupons are either digital or printed off from my purchases. Apparently my transactions were flagged as suspicious and I have been accused of using customer coupons. I have no idea how this is a possibility. I am most likely going to be terminated for this as I am on suspension right now. I have all my receipts and all the proof to prove that every coupon and discount I have used is my own.

I’m just putting this out there as a warning for any other colleague who may be couponing. I guess it is a fireable offense now.

EDIT: I made it out of this alive. I am resuming work at the beginning of the next pay period. Do not touch those $3 coupons may as well store use a lighter and burn them (joke).
