I love the new towers! I have full 3G signal all through San Andreas and the internet is Super fast!

I had no complaints until 4-16-2011 when I experienced No Service message all day about 9:30pm I had 1-2 bars tried to call my mother to let her know what was going on this is my only phone. My mother is 83 and lives alone and I also live alone and I just had achelies tendon surgery. While we spoke I lost service again. On 4-17-2011 I called AT&T and spoke to customer service I was told a service tech would call me as there is a problem in my area. I am still waiting for that phone call. I found out yesterday that people are having problems reaching me. When a friend called me the phone would ring a couple of times and stop on my side I never knew it rang as I did not hear it and there is no record of a call. When he was finally able to leave a message it showed I had a voice message but not that a call was missed. This person was very upset he could not get through to me because his wife has a high risk pregnancy and was in the hospital. He told me that later when he had car problems the tow truck driver was also having problems with his phone. What is the problem AT&T?
