My payment is not being made through Goole store.

Hello. I'm korean. Please understand that I am not good at the English language. I want to cancel the plan, but I'm having trouble becasuse I can't. I am using Adobe's own product, and payment is not made at Google either. It has already been confirmed through a Google counselor. But Adobe asks me to solve this problem in Google store. Where should I solve this problem? I talked to already Adobe counselor about the cancellation of the plan, but I only got an answer to ask the Google store.
