I have 4 phones with AT&T. My phone frequently has dropped calls, poor connections, or no service available. To complain and get support is so time consuming and nothing is resolved. I have overcharges on my bill and again to get it adjusted is so time consuming. There may be a partial or no adjustment for the overcharge. I yrt to uprade my phone and they mess up the order and it gets cancelled. Now I try again to upgrade and they say I already upgrade. Every time I try to get some resolution with customer service it is a long wait, - I get transferred one or more times - wait again - with little or no resolution. Why do I not switch? The three other phone users think the phone is OK and other services may not be any better. If I had the time I would sue them for breach of contract.
