Paytm Mobile Solutions — violation of data protection and refusal to close/delete the account

Address:	Kangra, Himachal Pradesh, 176213
Website:	paytm.com

As of 21st november 2017 i submitted a request to paytm to close my account. I received an answer that the account cannot be closed, but only blocked. That means all my private data are stocked into their system without my approval. I found this issue that is violation my rights of data protection. I want to close the account, but there is not that option.
The option of blocking the account is only if i send the proof of my bank statement where i made a transaction with paytm. After so many exchanges of email and the same standard replies, i said i cannot send the bank statements as this is something private and the company has no rights to ask for such an action.
Therefore, i ask to be helped to force the paytm company to immediately close and delete all my previous account data and stop asking information about my bank statements
