Billing and other accounts

I'm seriously tired of Xfinity with these charges soon as you pay one bill another one pops up then to find out you guys let someone get an account in my name in Memphis and one of your agents claim to remove it then others say it's nothing on there and my bill is over 300.00 and all I have is internet and home phone ...no one can explain these charges and I've been on the phone for 3 hrs now because you have people that can't comprehend and keep hanging up on me. I'm ready to start a class action suit at this point I feel it's something shady going on with you all and reading the rest of these complaints I'm not the only one with false charges your retention department roda  just hung up and did not call back this makes call number 7 that I have to call back now
