paid off my iphone early. they charged me one month more than I owed then charged me another payment on my next bill which they will not refund. I have been asking them for over a month to unlock my phone but so far they will not unlock it. I am truck driver and their phone service is substandard. dropped calls, garbled connections like back in the 90's.... not a recommended service provider. We have their wifi at our home and it is just about worthless as well.
