Update - they just called back AGAIN. I called them back and they gave me the runaround saying that it will take 30 days to remove my number from their system. Typical Charter BS.
Dumb guy from 'charter' called at 9pm. I was so irritated that I answered the phone to confirm that it really was a prank. He stated they wanted to know if I was receiving the best service. (How would I know if Charter was giving their best service) His question was what do I usually watch. I asked him on my computer or tv. He said umm. I quickly replied I am not going to answer your questions and that I had to go. He started laughing and I hung up.
Have been getting calls from this number on and off since the beginning of the month, never leaves a message. I called the number back Charter Promotions, talked to an idiot named Brian. Told him I wasn't interested in Charter services and to take my number off their list. He said it would take 30 days to take my number off their call list. What a bunch of BS. when he asked me my name I hung up on him. If you don't know who you are calling then it must be some auto dailing going on.
