Unresolved Xfinity Mobile Billing Dispute – Request for Private Support

I have had the same EXACT problem but more! When promotion expired, I was going to AT&T fiber optic right. Asked xfinity since have been loyal for period if they are willing to give me something an incentive free but anything to remain their customer. They gave me free Andriod phone lk A37, I have screenshots of entire conversation before signing the new contract with arsheet guaranteeing all is being recorded an it will be free no fees, an included much of streaming services as well. After few months before traveling to Fuji, Im an influencer so I decided I'd use the andriod since my iphone should go. Find out it's locked by carrier, contacted rep. He explained reason i call everyother month to get $15 wavied is the mobile line not using or ever had. Once this is canceled it will unlock, I asked him are you sure. Legally & logically makes sense, an 
I agreed. It didn't unlock, contacted mobile after 5 hours on phone. She did her research an assured the store tech will unlock it. After $62 lyft charges going store exchange my modem xb8 for this xb10 where awesome said the store had in stock. Didn't have stock, an employees their said it will take 72 hours new modem ship & mobile to unlock. Nothing ever happened, following day, contacted xfinity again only to be told since i canceled mobile plan they wont unlock carrier. I have proof from chat with agent prior to entering new contact, where small claims can handle this is seconds an it clear xfinity is running a money scheme on customers. Two days i got email "A correction to your Xfinity Mobile Device Payment Plan Agreement." <----------------- Are you serious?!! Correction is term used, & have no email of ever having a device payment or agreement. They decided to put this in, an if we dont stand as consumers together, screenshoting, recording (only if legal in one party conscent states) to protect yourself, an if xfinity changes or decides to not honor promises or incentives keep customers. Dont be afraid to bring them to small claims, you will WIN!!!!
