Videocon Industries — Cheating customers with fake credits.

From last 2 months, videocon d2h is deducting fake credit amount from my account without any intimation to me by any means. Whenever we call in customer car the only thing they say is we cannot give any information to you and you have taken credit from us but i can give in written that no credit request is initialized from our side.
The company is fooling the customers by deducting fake credits as i have not initiciate any credit request and after last talk with customer care executive the service of credit money was also stopped.
Still money is deducted from the account.

I have continuously asked for proof for this credit amount on email or sms but not details are send to me. None of my previous mails are reverted back by the company.

I want clarification for this as this has become an harressment for us.
