Xfinity Mobile - Contract deception

One cannot trust anything coming from xfinity mobile staff. They will say anything to get you to transfer your service over to them. Agent Amira did a wonderful job of explaining the plan I would be on and subsequently sent me a contract that outlined everything as she had explained it. Once I approved that contract, I proceeded to transfer my line (which was not without its issues but I appreciated her patience and constructive manner). Following the transfer, I logged into my account only to find that I now had a new contract that indicated that my bill would be $65 higher than was explained to me. I called customer service, spoke to a Manager called Yemi who simply told me that this was their policy and that there was nothing he could do to rectify the incorrect information I had received. He made no attempt whatsoever to be helpful despite the fact that this was not what I ihad agreed to over the phone and neither was it the contract I had signed. How is it acceptable to provide a contract before someone transfers their line that specifies one amount and does not outline any additional costs for subsequent billing cycles and then generate a completely different contract after the person transfers their line, with a new amount and new stipulations? That is the definition of deception. Do not trust anything you hear from xfinity mobile staff.
