I had really worst experience with MTS service. I used MTS for 2 months and the connection is really poor. I told to disconnect my card, before next bill cycle. After I paid bill, they still sending the bill. I asked why its not disconnected. They like "its just temporary disconnect". So, in future if I change my mind and come back and use or transfer to some other person. I told to disconnect permanently. Again they disconnect only if I pay my due bill. Its like paying again for no reason.
I refused to pay the bill. They told they take legal action for non bill payment. One day an Advocate called me from Delhi court and threatening to pay the bill. Seriously! these people are BIG scammers, they know how to scam people from A to Z. We should take this seriously and raise this issue.
They campaign to sell the card. Bad costumer service. Poor connection.
