Flipkart — Unblocking my flipkart account

Flipkart has blocked my account without informing me. After mailing and contacting customer care many a times they are telling just due to high returns they blocked.
But inspite of being plus member I ordered one wallet and they gave me wrong wallet and as I was placing return they blocked according to me but they are saying due to high returns.
They are still delivering me products but no refund is being given by them not I am able to exchange my product because of size issue.
Please unblock my flipkart account sir I am not able to order anything from flipkart. My orders are pending and my money stuck in flipkart too. Please do help in unlocking my account.
