Flipkart — my account was blocked without any notice or warning

I got a mail from flipkart customer support service that my account is closed due to high return.
They've not mentioned anywhere that one can request for how much returns within a month i[censored]ser exceeds this number then his account will be blocked.
I'm also a plus member of flipkart but they are not replying of my mails. They just copying & pasting same information every time given as below.

Hello,

We'd like to let you know that your recent order (Od[protected] has been cancelled as our systems have detected an unusually high number of returns in your purchase history. This would also mean that you will no longer be able to login to your flipkart account.

I requested him to give back control of my account and thereafter i'll take care about return requests. But no response received from support team.
