Nightmare - I plan to cancel and go back to Tmobile

Just had the worst experience of my life.

Had Iphone 15 Pro Max 256gb with cracked back glass. Been paying Xfinity Mobile Insurance for over 3 years since I joined. So I decided to send in for replacement via Xfinity Assurant... Worst decision I could have ever made. I was sent a Iphone 16 Plus 128gb Black... Assurant said that phone back since it was the wrong model, color, memory. via live chat since I was stuck with no phone.. I sent it back, so they could send me the correct phone... When I contacted Assurant they kept saying nothing they could do for days until I finally go a hold a live person by using my wifes phone to call Xfinity to transfer me to Assurant live person... After begging and pleading they sent me another Iphone 16 Plus (this time color was ultramarine which is a color I hate). I was without a phone from November 2 to today November 12..... Ive called Xfinity Mobile took me an hours of going through same story and just be sent in circles, to internet retention not mobile, back to agent who want all information again and says nothing they can go for me. Each time I call Xfinity after hours of begging to speak to a manager with customer service, after numerous holds, they tell me there is no manager or retention line or anythin they can do  for me.. After so many hours and days of this exhausting horrible experience, I feel stuck with this stupid blue color, Iphone 16 Plus 128gb, that wont even allow me to take a picture or download an app because a message keeps popping up that I need to buy monthly storage since my memory went down from 256gb to 128gb.... I couldn't set up eSIM so had go into store to setup eSIM, nothing Xfinity in store could do, busy and could care less... Im feeling super defeated, loss for word and energy....

Now, Im finding out Xfinity doesnot sell any phone equal to my Iphone 15 Pro Max 256gb.....16 Plus only comes in 128gb... 17e 256gb has enough memory but no where near camera and other features.. so iphone 17 pro max only phone available that could replace my phone which is $165 + $33 x 36 months... Xfinitny agent made it sound like it was only $165 without mentioning the monthly... I had Tmobile before this for 15 years and I remember if something like this would happen an Tmobile Expert would probably be taking care of me with the iphone 17 pro max at this point.. Im planing to switch back to Tmobile were there was better customer service and appreciation for customer loyalty.

Still lost for words, I could be treated like this, and customer service, and my entire experience...... The hours, exhaustion, tears, frustration, going in circles, no empathy, such low customer service, and all of this falling of deafs ears.
