Worst customer service ever, switching immediately

I talked to 3 Xfinity agents today. 4 others previously on the same issue. All I needed was my Xfinity mobile account to reflect my new address. I moved a year and a half ago and transferred my Xfinity internet to my new house but Xfinity mobile still showed my old address. Because of this I could not order a new phone. 4 previous agents all told me they fixed it and it would reflect on my account shortly. Well those were all lies so I decided not to upgrade my phone. Well now I need a new phone so I decided to try again. First agent said he fixed it and it would reflect in 2-4 hours. Well surprise, it didn’t. So I reached out again and the new agent I got said it showed the correct address on their end but they would help me order the phone to the right address. I go through the order and once I received the confirmation email it showed being delivered to the WRONG address. I told the agent it was wrong and they kept telling me it was right.Well im not paying for a phone that I won’t receive so I asked them to cancel. They reassured me multiple times it was canceled and when I asked for confirmation they ended the chat. I get connected to a new agent who tells me it wasn’t canceled but they canceled it for me. Again, when asked for confirmation they ended the chat. I wanted to let you know this so maybe you can better your customer service. This is why I will be canceling both my mobile and internet services through you.
