Videocon D2h - Cheated by D2h

I am a videocon d*h user with customer id [protected]. Since from last * and */* month, I am facing n no. of issues regarding services of Videocon d*h, which includes wrong add-on activation, frequent unfair balance deductions. The fresh incident is regarding my recharge of Rs. ***.** for which I should get services for ** days but they have deducted * days for no reason. Again I have complained to their email id's-customercare@d*h.com, Albert. Lobo@dishd*h.com (Nodal officer), ceo@d*h.com, anil. Khera@d*h.com but to which they are not replying. These kinds of issues happened in the month of April also & I continued their services on their assurance of clean services in future but to my disappointment, it has happened again.
As it's happening frequently I request you to intervene & provide resolution. Lodging complaints again & again aren't feasible with Videocon d*h. They keep our call on hold for the mammoth duration (** min). Sometimes call gets disconnected & they don't bother to call back. If we write the email, they simply avoid replying to it. Now I am so furious, that I even don't want to use their services but unfortunately I have invested money in buying their useless products. I want my money back for the investment done on their set-top box & umbrella. I hope needful action will be initiated from your end & strict action will be taken against Videocon d*h.
