Canceled Plan months ago, still being charged

I had canceled a Photoshop plan on my enterprise account in April, because I got myself All Creative Cloud Apps subscription on my personal account. I have still been charged up until now for my Photoshop plan which I have received a confirmation e-mail for when I cancelled it. Now it says that I have a Photoshop plan, but there’s no way to cancel it. I have tried the chat bot and I called the help line.

I could barely hear the person on the other side of the line, I could hear my voice echoing back to myself louder then theirs, not mentioning the constant background noise. I tried to spell out my e-mail 3 times but they kept telling me I am not in the system and don’t have a plan. I was on another line earlier, with a very helpful person who told me that they found my account and can see that I have an enterprise plan and they will redirect me to the relevant line to handle this with all of the info. But alas..

I am very frustrated. I have cancelled a plan I am still paying for. It was cancelled before a yearly term would kick in, so it’s not that. The customer support experience has been even more frustrating...
