activating mobile phone

I recently purchased a new phone and plan through Xfinity. FedEx delivered the phone to someone else's address and I never received the phone. I promptly called Xfinity and explained what happened. I was told that the phone could not be activated and they would take of a refund and then I purchased another phone. I did receive that phone and proceeded to activate it. I was having difficulty so I went through online chat and provided all the information needed including a transfer PIN from my previous carrier. I was assured that the phone would be activated within 24 hours. My phone was still locked. I again contacted chat because I am without a working phone at this point. It turns out the phone that was activated was the phone that I never received! After another 2 hours and help from the advanced team they came up with a solution to fix the problem and get my old number back. They had to get permission so that took a couple of hours. Now I am speaking with the 5th assistant. He proceeded to set me up with eSIM and we begun the activation process. It seemed to go through and showed that I was connected and he told me I should receive a push notification through the Xfinity app in about 30 mins to finish activating. It has been a couple of hours and no push notification and while my phone is not locked I am not connected to the network. This is beyond frustrating and is all caused by one person who did not pay attention to what they were doing. I need help ASAP!  I am a cancer patient with no working phone and  I was supposed to start a new job today which is not going to happen now.  I have spoke to several people and still have no service! I need some guidance on what I am supposed to do.
