Xfinity internet connection is the worst!!!

Xfinity has the worst internet signal I ever used, have to reset my internet almost everyday. when i called the customer service, she kept telling me it was issue from the router not the internet. what an cheap blame. and she said if she sent a man down there to check my internet issue will cost me money.  if you are the person who has to call to ask for internet reset every single day. you won't say thing so easily.
