I had charter for telephone service and cable service for 5 months. During those five months my phone would drop calls constantly.
At first it was just a few calls then it got worse. I would call Charter service and make an appointment and wait all day for them to get there. They were good about getting there at least the day they said they would. The service tech’s were nice enough and citreous. The first one checked what he could, scratched his head and said everything was fine and if I had any more problems to call. The phone problem got worse and I called again. The second guy was really nice and at least tried to do something. He turned up the power on the modem they installed and of course said if you have any more problems, call.
The phone and the Internet got really BAD everyday at 4:30 PM the Internet was so slow you could not send an e-mail with out the Internet dropping out. If you made a phone call or someone would call me same thing would happen, the call would be dropped. This would go on till 8 to 8:30 PM then it was an "if'e" thing at best. The Internet would work long enough to check emails and maybe send one or two.
I finally got the service manager to come out an check it him self. He did nothing except say, “Please give me 5 day’s to get it fixed, we grew to fast around here and our system can’t handle everything”.
After 3 weeks of the same thing I finally got tired of the situation and called Bell South. They came when they said they would and changed the phone over. It was about 4:45 PM when they did it so it was a great time for the test. First thing I tried was Internet; it was like having FAST Internet service, wonderful! I have not had a problem since then with the phone or the Internet and will be talking to Bell South about fast Internet.
I am in the hills of NC around Asheville so this is just in my area. Charter may work where you are. Good Luck!
