I've read a lot of posts of people cancelling their AT&T cell service as well as DIRECTV. I work as a network engineer and the company I work for was recently forced to switch to a different WAN provider. We were with Sprint and T-Mobile is eliminating the service after they purchased Sprint. I lobbied HEAVILY against using AT&T based on their cancellation of OANN amongst other reasons. I've lost count of how many times I've worked for companies that at the first opportunity AT&T has screwed their clients. We ended up signing a contract with Verizon for our global network.

So like you, I'm doing all I can do. They have gone woke and I'm willing to bet their gonna go broke in a hurry. For a service provider, they really suck at service.
