How can I change my service, can it be done online? I dont like calling 1 800-xfinity, waste of time. I currently have Internet, TV, and Home phone. I want to reduce my monthy cost, it keeps going up. If I need to to change my service provider to e.g. AT&T, to significanly lower my monthly bill, I will. I really do like Xfinity, but maybe it is time to change, cost is getting rediculous. Help me out and retain a good customer.
