You guys are thieves, if anyone sees this post, stay away from Xfinity mobile

I would give negative stars if I could.  You guys are thieves!  Sent me an iphone 15 pro that I sent back so I stayed with Verizon.  Says that they never received it when they sent me the return box and label. Charged me for the entire phone and now, even though that IMEI is not under my name or any account, won't refund my money, you guys are horrible.
