xfinity is charging me a transfer fee

I was changing apartments, still the same address, I tried moving my services to the new apartment with a chat agent but we lost connection. I called and spoke to an agent and they scheduled the move. I specified no new equipment was needed but they still shipped more out. When the installer came he had a very hard time with accessing our account and called his supervisor. He proceeded to install the new equipment and he took my old equipment. A few days later I got emailed about my bill, it was 161 and it changed to 609! They had also creating another account for this same address with a different wifi plan as well where I got charged 124. I chatted with several agents all of which kept transferring me back and forth and then just left the chat. I have spoken to 4 other agents by phone as well. 1 assured me he would submit a ticket to reverse the transfer charges. The second one also couldn't do anything except credit me $60. the one from today kept making no sense and contradicting herself with the excuses she gave me for the charges. In the end, nothing was resolved they want me to 549 and my request for a supervisor call was basically ignored.
