Xfinity Mobile deceptive marketing, fraudulent charges and stole my iPhones and never provided trade in credit

I traded in 5 of my iPhone 15 as device credit so I can get the iPhone 16’s for my family.  They never applied any credits, stole my phones and I’ve called 9 times and each time on phone for over an hour.  Every single time they tell me something different but pretty much they’ll make up any lie to buy time because the offshore employees have no clue what they are supposed to do… their entire is very poor and they don’t understand the issue,  but a few times I spoke to someone who did and made multiple ticket claims with 0 resolution. 

im honestly desperate and stressed out of my mind with Xfinity mobile and honestly don’t know what to do at this point.  It’s been 4 months.  I’m going to file a fcc complaint, a bbb complaint, and see if I can file a class action lawsuit with other customers which have similar issues.  A quick google search showed this has happened to hundreds of customers.
Xfinity mobile is the bigger fraud out there… I’ve been a Xfinity comcast customer for 17 years.  Joined Xfinity mobile as soon as they offered mobile service but over the years it’s been nothing but bad service and excessive charges. 

literally stole 5 iPhone 15’s.  They did the same thing a few years ago but I let it go,  but not this time, I could have sold those paid off phones for a couple thousand dollars.
