I am very unhappy about T-mobile one policy. I renewed my contract(Only sim) at the beginning of the August. And seller told me I can renew my contract with a phone contract. But he did not clearly tell me I could not renew the phone contract if the new contract has not started. And my new contract will start at 26-sep. But at that moment, the promotion will finish. Therefore, to me, it seems like 300 euro lose in total. I went tmobile shop, and called customer service, they dont stand at customer side to think. Just fast reply to say they can do nothing, sorry. So now i try forum and sent email to customer service to see if you have some special solution or at least reflect this to your mangers. Customers are loyalty to T-mobile, therefore T-mobile should stand at customer side let this group participate this promotion.... Now i am very unhappy and start a bit angry now.
