Directv unable to process refund

So, I have to say that I am appalled at the lack of support from Directv over the past several months regarding my situation. So, here goes. For whatever reason, I had two accounts activated at the same time when I only needed one and was charged for both. I was unaware that it was being billed as two accounts and I did not think anything of it because even with the double charge, it was still much cheaper than my other cable/internet in Florida. I just thought it was a win. 

When we canceled the account to move overseas due to a military move in September 2022, a customer support rep informed us of the double account and told us we were owed nearly $1,800. Yes, I typed $1,800. That isn't a small amount of money and I was told that after we got settled overseas to contact Directv, which we did and a check would be mailed. After about 8-10 weeks we reached out because we did not receive the check. It was not a big deal because mail does take time in our location and it was out of the question for items to take a long time to arrive. So, after 8-10 weeks, we contacted them and were told Directv does not send checks and can only refund via the card on file. Well, here we go. After nearly 20 hours of phone calls and being 6-7 hours ahead overseas, we are still without a refund. We have spoken directly with multiple individuals at Directv and have been told that it is our mailing address that cannot allow the refund. Well, that is not our issue because we have to have it as is to live in our location. That should be on Directv to validate, right? We asked for a check and have been turned down several times. I have been told multiple times that it would be processed and multiple times we have been lied to and no action has been taken. I almost feel that it is futile but $1,800 is a lot of money and it is my money. I understand that many of the employees I have spoken with empathize with my situation, but when individual employees give me their ID number and the interaction ID and then ghost us on the back end when we need them to follow up and follow through, we get nothing. 

While I was in the United States last week, I went to an ATT store and while I was there, the customer rep called Directv and overheard the employee, whose ID number I will withhold state, "The refund will be processed in 3-5 business days." That was 7 business days ago and here we are with no further results. It is pretty upsetting that as a military member living overseas, I have to jump through hoops to talk to a supervisor on the customer service line, and each time that I do I get different responses. That tells me that there isn't a right answer, but an answer that will get them off the phone the quickest with the least amount of work. At least four times I was told by an agent that I would get a call back within an hour and it never happened. The customer service is atrocious.
