We have had DirecTV for years in Florida. When we moved to the mountains in North Carolina, we found that our new house was connected to Charter Cable. After reading the reviews on this web-site and seeing Charter's rating in "Consumer Reports," we were horrified and immediately called DirecTV. Sadly we found that we had trees and a mountain in the way of their satellites and that was the end of DirecTV.
That's when we reluctantly looked into Charter. We found out the TV, broadband and phone bundle, was an extreamly good deal!
While we have had some minor problems, which keeps me from giving them a five star, but it seem Charter's customer and technical support teams have been reading these reviews too, as they seem to go out of their way to be polite and helpful, and are knowledgeable on their products. They have even given me assistance on computer problem that are only partly connected to Charter's service.
I think the key in dealing with Charter's Customer Service is: if you don't pull an "attitude" on them, they'll "bend-over-backwards" to be helpful to you.
