Refund never received, sent to cancelled credit card, bad service

I am honestly surprised at how bad this experience has been, as a faithful user of Adobe suite for 10 years.

A month ago, I changed my credit card on the account because I was cancelling the card I had at the time. 

That same day, later, I wanted to cancel my account, and instead, accepted the discounted deal and was told I'd receive a refund of 33 dollars. 

I never received the refund. I have written to customer service in chat a number of times, and found out that they issued the refund to my cancelled credit card?? Which I had already removed!! So, how they even had those details still strikes me as very odd.

My complaint was met with derision and constantly being told to ask my bank. I did ask the old card company, and of course, they never received a payment. The adobe team seem to not believe me and not bother to check their records. They sent me a receipt that proves it was sent to my cancelled card, but insisted I check with my bank again when I asked. 

I still have not received the refund, and feel that if it is a false promise, just don't offer it to begin with. And don't keep customer card details after they have been deleted. 

I hope this can still be fixed because I'd like to remain a customer of Adobe. I just want better service and my 33 bucks. Thanks.
