Flipkart - Flipkart account blocked without any reason

I was using Flipkart account with the no associated ********** , and it has been blocked all of sudden , which is very bad. I had almost more thn **** supercoins and so many purchases linednup. Which now I cannot replace or return. Complaint on customer care number they said they can't help me regarding the same as they have no such policy. This is really a fraud now Flipkart is doing. If seller is cheating on us as a customer we have full right to replace or return the product. If because of so many numbers of return and replacement in my history Flipkart is blocked my account thn they has no right to do it to anyone.i wasn't my account to be unblocked from Flipkart saying sorry. M ready to fight .
