iPhone was blacklisted by Verizon and got it removed from the blacklist

Had similar issue. Been TMobile subscriber for 17 years. On Wednesday 10/4 my esim (imei2) showed SOS only. On checking online through imeipro.info transpires that Xfinity Mobile, a company with whom I have no affiliation or relationship had accidentally blocked imei2 they acknowledge they made a mistake and promise to sort this out. I have addressed a letter to the CEO of Comcast and a second letter recently addressed to him. It's now 16:12pm on 6 October and I still have no coverage. My phone is still blocked. I've checked again online and it shows it's still blacklisted. Obviously it's now clearly apparent that Xfinity mobile. Don't know what they're doing. This is no different to somebody coming and stealing your car and then realizing that they picked the wrong car and now want to return it to you at the date that suits them. This is unacceptable. The next stage this evening is to write a letter to the FCC and start handing matters to my attorney and claim damages above a new phone.
