Ali, the customer rep went out of his way trying to help me with a problem on a new phone from US Mobile. He tried for 4 hours with no positive result. Phone was bad out of the box. Only recourse was to return the phone to US Mobile but it would take at least a week to "check" the phone and return it to me.....the fine print in the return letter stated that I must accept a restocking fee of 50usd if they could not find anything wrong with the phone. This is the same phone they sell for 38usd on their website. I closed the account, returning the phone and contacted my Credit Card to stop payment on all charges from US Mobile. Extremely poor USA customer service as there are NONE!
