be aware new scan xfinity by customer care

This is how I deal with a new Xfinity fraud.
After agreeing to switch my Google.fi number to Xfinity, I received a phone but was given a new number by default. I messaged my account number and pin to customer service, but it took more than 10 days. When I attempted to transfer the number today (6/8/2014), the agent informed me that I may cancel the number that had already been issued to the devices. I accepted, then they cancelled, and now they're misleading me because, according to the agreement, they issued the number by default, and there's no way I can swap. To change my number, I now have to pay the entire fee for the device.

policy :-

"If line is canceled, voluntarily or involuntarily or device payments are accelerated, balance of credits associated with device payment are forfeited. Offer not valid with prior purchases, returns or exchanges. May not be combinable with some other offers." by default they provided the number no way i can switch? to change my number i should cancel the existing connection "
