Charges

I am getting charged for service that I'm not receiving.  I have called several time and my online accounts say that the internet services is canceled but I'm still getting charged for the services.  I haven't had internet service with AT&T since September 2022, I stayed on the phone with a Representative about 3hrs. Until I was stressed!  I'm a Senior citizen on a fixed income and can't afford to keep paying for service I'm not getting,  I hate to have to take Legal action against you but I don't know what else to do.
