Loss of channels

AT&T has failed to properly prepare for the  anticipated end of contract negotiation with Nexstar - resulting in the loss of ABC station, a MAJOR network. This continues to happen, as in the past, when other channels were removed from the lineup - as your customers continue to pay increased costs in service. We set up another TV(purchased an antennae) that would give us this basic channel for the interim - assuming we will get the channel back at some time in the future!  I think it's time to contact other providers who can provide continuing service that we PAY for and don't get with AT&T.
