How is this legal?

I am so exhausted and tired of dealing with Xfinity customer service Representatives. I've been dealing with this issue since Sunday night it is now Wednesday midday and I still don't have a working phone. I've contacted nine different times spent hours on hold and chats just be lied to repeatedly and I still don't have a working phone. Xfinity messed up initially and still cannot fix the problem.  I am so stressed out. I have asked several times to talk to managers and I was on hold an hour and a half and got hung up on and I've spent hours and hours on chat just to be told the problem would just be fixed and nothing happens my mother-in-law is in the hospital for back surgery my mom has Alzheimer's and I can't contact either one of them yes I don't have a stupid phone.

My current phones were supplied by Xfinity mobile. Xfinity mobile sent me a new phone to replace my wife's. When I activated the phone it somehow took my number from my phone and put on the new phone. I simply want two numbers switched to two phones and it doesn't seem possible.  Either Xfinity can't or won't do the basic minimum and so much time has been spent trying to fix this problem. Meanwhile I'm losing business and sleep spending hours and hours and hours dealing with this problem all the while paying Xfinity for service I can't use. How is this legal? This is a breach of contract. Beyond frustrated
