Furious with Xfinity Mobile and want a resolution

On Saturday, August 9th, I went online to order a new iPhone 16 as an upgrade for one of two phones on my current mobile account. When I went to enter in the shipping address, it would only allow me to ship to my home address although I'm on the other side of the country and need the phone NOW. The "customer service" rep I called on the phone asked me if the home I want the phone shipped to is on Xfinity internet. It's not. It's my mother's and she's Spectrum. I thought it was ludicrous and asked what earthly difference it made and was informed that Xfinity only ships to addresses using Xfinity services, which I don't believe, and it's the case, what a stupid business model. When there was no email informing that the phone had shipped, I called yesterday, August 10th, and asked that the phone be shipped to me in North Carolina, where I will be until the end of the month, and not to my home address in California. Once I worked my way up the chain to a supervisor, once again being thrilled with the "customer service, " I was informed by a supervisor that there was nothing she could do. However, it was not until today, August 11th, that I received information and a FedEx tracking number from Xfinity, which shows the infomation was provided to FedEx TODAY, not yesterday or Saturday when Xfinity had no problem takiing my money, and that has still NOT shipped. I want the phone shipped here, and barring that, because I don't expect anyone at Xfinity to give a euphemism for carnal knowledge, I want some type of compensation/upgrade for the decades of money I've poured in your coffers only to be treated like excrement time and time again. The fact that you have a tag in your drop down menu that is #customerservice #terrible #annoyed really says it all. And this is a complaint both about the device not coming where I need it, but also about my current plan.
