I bought MTS premium broadband connection and using it for last 2 month.They offer unlimited internet connection for Rs. 999/-. As per the advertisement I paid the amount for the connection. When I connected its shows that data usage provided for me is 30GB (maximum data usage for Rs. 999/-). I don't know that the word unlimited means maximum of 30GB.MTS start cheating me from the beginning itself. They cheated me on:
1. Bad connectivity
2. Only 30GB usage for unlimited plan
3. When we use 12GB out of 30GB the speed will cut down to below 115kbps from 3.1Mbps

When I call the customer care I got the respond that for unlimited plan 3.1Mbps speed was only available for 12GB after that the speed will reduce to 115kbps(but the advertisement shows that ''UNLIMITED DOWNLOAD AT A SPEED OF 3.1MBPS'').I don't know what to do?.Please help me...
