New account and activation

Customer service was awful to me today. I moved to Augusta Georgia and moved into a duplex three weeks ago. I researched Internet was told Xfinity was the best. I go to call to see what I needed to order and they get all my information and there was something with a person with the same first name is mine that lived in this duplex 2 1/2 years ago, so therefore they wanted me to verify my Identification to get an active account. So on December 11, I do all that takes about an hour, thought everything was situated. They even shipped out the modem. Received the modem this morning. Go to hook it up activate it was told that it can’t be activated. My account been deactivated. Call customer service. They put me through all this stuff saying that I need to verify my identity again and that way that this person‘s bill who lived here 2 1/2 years ago, that is not me will be dropped off of my new account? Someone make it make sense. I’m sorry I was born with a common name, but how in the world for somebody that lived in a rental community complex that I have the same first name is mine Their bill that they still owe is put onto my account and so I can’t activate my brand new service. This has been the worst customer service I’ve dealt with the worst decision that I have made and not to mention they put me through all of this before they even shipped out the modem and now you tell me, I’m so sorry that your name matches somebody else that lived in this rental community two years ago? Make it make sense cause if I would’ve known all of this I would’ve never put myself through the headache of trying to argue with Xfinity and then prove without a shadow of doubt that I am not this person just to Told I have to do it all over again sorry can’t have an account or activate my brand new modem. Horrible horrible horrible customer service to a brand new customer.
