How do I cancel my service??

I had your service through AT&T which was canceled on March 5, 2024. I moved from that address on March 1, 2024. All the equipment was returned to AT&T, at their direction, on March 18, 2024; therefore, I have had no ability to use your service. I just received your bill to my new address forwarded from the USPost office received  on 6/13/24. The post office in our area has been running behind in forwarding mail up to over 45+days. This was the only bill received from you. I checked with AT&T and was told by them that the directv was canceled by them on 3/5/24. My house on Etching Overlook has been empty since 3/1/24. Please change your charge to zero dollars since no service has been used. The  account is listed to Cliff Kimsey, my husband who has dementia, (edited per community guidelines). I tried to get your service at the retirement village but they don't allow dishes on their facilities. Please respond when this is done. Thank you for you attention to this matter.
