Charged 2 Technician Fees After Being Forced Down A Rabbit Hole

Hello! I was charged 2 technician fees after being told the WRONG information and given the WRONG solution twice. First of all, I was told that my apartment was able to run Xfinity internet. I bought the internet, set it up, did NOT work. Why was I told I could use Xfinity internet if I couldn't? Scheduled technician, he told me to replace equipment and if that doesn't work to schedule ANOTHER appointment. I replaced equipment. It did not work. Scheduled another appointment. This technician did something outside. Said if it continues to not work, schedule ANOTHER appointment and specifically request a "maintenance" worker. It did not work. I did as instructed. Except when I spoke to support to "specifically request a maintenance worker", the employee on the phone told me that customers CANNOT request maintenance workers and ONLY technicians can schedule them for customers. So I was given the wrong information AGAIN and yet another technician came out with NO FIX. The employee then schedules ANOTHER technician to visit. The 3rd technician basically does nothing. He looks outside, comes in and tells me "it's the wiring in your walls, you have to get your apartment to rip your walls open and get new wiring. It could also be possible this apartment doesn't support Xfinity"... What? So basically, I was told to the internet would WORK before even purchasing the service, then told to schedule THREE whole appointments, with 2 technicians being completely incorrect and useless, and the 3rd one telling me that it turns out I COULDN'T use Xfinity internet after all.. unless I of course rip my walls open and get new wiring.. IF that even works?? Now I am being charged $200... with no internet and no solution. May I speak to someone to PLEASE remove these charges?
