I've had a pre-pay phone for a couple of years, went to Car Toys and got a Note 3 (good $$), because they did not understand the system and checking the box that would transfer a pre-pay to a post pay, they added the phone with a temporary number.
I went to the Verizon store in Fife, Washington and Alfonso took the time to take care of the transfer or so we hoped.
The pre-paid was merged with the new post-paid account with the Note 3 and what was supposed to happen was to transfer the pre-paid number to the post paid phone and then delete the pre-paid phone. It did not work out that way even though they said everything was fine.
Now I have a Early Termination Fee on my bill for a phone that was not terminated but because the temporary phone number was.
