Unlocking My Device

I feel Xfinity is intentionally keeping my phone locked. My phone has been paid off almost a year. I ported my number over and the Carrier lock appeared. I have been to Xfinity store 3 times, spoke to over 20 reps, and contacted Apple Support! I have multiple ticket numbers and None of them have unlocked my phone!! All my information is erased and my phone is still locked. I don’t have access to emails, phone, messages, or credit cards. Everything is sending verification to my phone number (already ported) or my email which I don’t have access too. I have read several reviews from multiple customers with issues similar to mines. I have lost thousands of dollars in the past 4 days by not having access to my device. I will be reporting this information to FCC and filing a civil lawsuit.
