ACTIVATION NIGHTMARE! PLEASE HELP!

UPDATE! A year, yes a YEAR later and NOTHING has ever been resolved! My Straight Talk phone number was never ported over to Xfinity. In fact, no attempt by Xfinity has ever been made to port the number. I still have not been able to get a Kentucky phone number assigned to the phone. I gave up on getting a local number and tried for one that at least has an area code for Kentucky (the state I live in!) But that was also unsuccessful. The trickery here is that Xfinity can (and repeatedly does) make promises they do not, can not, will not keep for the simple fact that there is absolutely NOTHING that you, me, the customer, can do about it! You see, I waited as instructed by cs for my number to be ported and by the time is was clear they were not going to port the number for whatever reason, I was stuck! Not only did I NOT receive the $300 Visa for purchasing the phone and porting my number (even tho it wasn't my fault they couldn't ir wouldn't port it) but also stuck in a two year contract for a $1200 phone that they refused to let me return for a full refund. In fact I would be lucky to have gotten a 50% refund because they subtract a $300 penalty for breaking the terms AND depreciation type adjustment, even tho the phone was only a week old, had never been taken out if the original protector film and only had one call made from it ( TO cs!). Then after all that, they still, at their discretion will only refund what they decide is an appropriate trade-in value. Minus the penalties and fees.
Trying to decide if you want to make the switch to Xfinity Mobile? DON'T DO IT! RUN AWAY AS FAST AS YOU CAN!
