Rude, uncaring and incompotent

First off I ported my number out of xfinity and discontinued service for the exact reason that I am typing here in this forum. I have spent 6 hours of the lat two days with multiple calls into support to get my phone unlocked. On the first day, I was hung up on multiple times with no resolution excpet that a ticket was opened and that I had to wait 24 hours for that to go through. Well 24 hours later my ticket was declined so I called to find out why. They are now telling me that I owe another $38.08 after I was told my account was paid in full. The worst thing that can happen is to have someone lie to you after taking their word for it and paying what was to be thought of the final balance. I find it very unprofessional that I was lied to and hung up on and repeatedly interrupted when I was trying to speak. I may be contacting an attorney when all is said and done. I also find it unprofessional that with all teh money that comcast makes that they outsource their customer service with agents that are rude and not very good at their jobs. And also deny employment to capable US citizens with many years of contact center experience. I hope this reached the corporate level executives that can actually or even care to reprimand the employees who were rude, uncaring and incompotent.
