I have bought a reliance data card in Bangalore, which was suppose to be 2 mbps speed. But after repetitive complain speed was less than 512 kbps I think. So I decided to disconnect it and spoke to customer care. They said that they will return the deposit (Rs-1500) within 2 month but that never happened. Even after visiting many reliance center including (MG road) nothing so far has happen.
So, I was right about reliance...very unethical approach towards customers.
