Flipkart - Flipkart blocked account and rejected return request

My Flipkart account(**********) got blocked due to high returns and they didn't warn me before ordering and rejected my return request. i ordered some products in *-* quantity in different colour on same date & they all got delivered on same date but i didnt like the quality so had to return all of them together. They said that there all multiple return requests so blocked account. But when i ordered either they should warn me before or first resolve the return requests then block it. they wasted my so much of time & money. return policy is upto *th january **** but i cant do anything.
They blocked the account with open return request without resolving them. i had loss of ****rs. Even customer supports are mailing same replies saying that 'We understand your problem but seller has rejected your return request'. i have not purchased directly from seller but from flipkart so FK is answerable to all my complaints. how can they put now everything on seller's head sitting and talking robotic language? Please help!
