Hi @Ravi shankar kumar 

I would like to help you with your request? Are you still in your contract period? If so, would you like to buy off your contract? If you’re not in your contract period than you can file a regular cancellation request. Please keep in mind there is a one month notice. If you could send me a private message with your 06-number, name, birth-date, full address and the last 4 numbers of your account number, I will help you with your request.
