Charged for direct TV receiver no longer have 2 years later

This sounds all to familiar to me. After calling in today due to my bill going up once again after a promotional period ended the very nice customer service person at DirecTV went over the boxes we had active in the house. That is where the nightmare began. We found that there was a receiver on my account still that had been returned 25 months ago Feb 2021. The receiver was sent back due to issue with device and we got a new receiver. We worked with technical support in 2022 to get the new one working and shipped the broken one back to DirecTV. Today I found out that the receiver I sent back we were still being charged for and is been 25 months of charges for something we no longer has. Transfered to tech support and they go receiver removed from account she offered a $25 credit in which I told her no way as I had paid over $175 for past two years for a receiver returned to DirecTV. She then got me to the billing department who was very unhelpful and down right rude. She told me it was my responsibility back then to not only speak with tech support to get the receiver swapped but I should have called the 800 number to deactivate the bad one, the one we sent back as they were different departments. We were never told this back then, since I was speaking with DirecTV technical and they helped with the swap and told us how to return the bad receiver that it was all taken care of. At no time did they say I had to call another number to deactivate the broken receiver I was sending back to them.  I was now told today nothing they could do as I missed my responsibility back the to call another department for a returned item. She saw it was returned and  not in my possession or in use since Feb 2021. She was very rude and instead of the $25 credit originally offered she said I will give you $14 which is less than first offer and way less that the over $175 I had paid for a receiver DirecTV has not me. She kept saying all notes I see is you worked with technical support and did not make an additional call and have not complained in 2 years. Well duh I didn't complain as I had no clue I was getting charged for something I didn't have which the customer care agent at DirecTV pointed out to me today. I was not aware that the 1 box we had his free with service it's the mini boxes we get charged for so the 3 on my account I thought 1 was for the main receiver which is why I said nothing until I formed today that no I should only have 2 I pay for not 3 like what I have been. The lady was rude contradicting herself while in the 0honeand then continues to go back to I didn't make another call besides tech support back then and they are not the same as calling to deactivate. Which again I thought I was dealing with DirecTV when swapping not that I needed to make another call. Now out over $175 with no help to resolve but $14 and 2 hrs of my time. So now I guess I go to Better business bureau to work on getting my money back that was stolen since DirecTV had this equipment for past 2 years and I have been paying for it to sit in there shelf. Then I had to wait online with rude agent while she processed the $14 credit that took forever she said if. I disconnected I would not even get that credit and she took her sweet old time. I got name of everyone I spoke with detailed dates of conversation from 2021 to put more time and effort into something they have had the entire 26 months. Beyond upset and going to write the BBB tommirw to get my money back.  There business practices are awful rude and take advantage of customers by not telling you process but continue to charge for equipment they show was returned over 2 years ago.
