I purchased a new charging cord for my Note 3 Samsung and found that it was the wrong cord... it has now taken me two days to attempt to return the card and I still have not been able to do it. Other customers are complaining bitterly about having wasted as many as two weeks to resolve a simple hardware problem. The staff is entirely unprofessional in demeanor and insists on taking customers in the order of their store entry rather than sorting easily resolved situations from the more difficult ones. I suggested that they implement a more efficient system and was accused of insulting them. This is a third party owner store and I managed to ascertain that the store owner's first name is Nadir. However the store employees refused to provideNadir's last name. They could not (would not) provide me with either Nadir's business card or his email address. The many customers who are disgruntled have absolutely no recourse.
Zero stars of I could. Switched to Sprint at the end of July, 2015. Received 4 prepaid American Express cards to pay off Tmobile phones. Staff is incompetent and lost 3 of the 4 payments. Company is a ripoff and scam saying I still owe even though I have proof from American Express that the cards were used at this store and the money posted to their account. Sent me to collections and killed my credit. Been trying to pay off this account since then with no luck. Lawyer is only next option. Stay far away from ANY Tmobile store.
