Kroger Cash Back

I have a question for all of you who are far more experienced with couponing than I am. I’m a long time Kroger shopper, short time couponer. I’ve been taking advantage of their cash back offers lately.

My issue is that I don’t think I was given the cash back last week. It’s been a full seven days. There is no where on any of my receipts, even the ones that I know I got cash back from, that shows it reflected.

Is there anywhere I can see previously claimed offers?

Kroger customer service was no help. They told me to look in the app and I had to tell them that cash back can’t e even be accessed in the app.
