Flipkart — Gave me fake product, rejected my return request and blocked my account

My registered number is [protected]...i ordered Adidas shoes and received different brand product..so i filed a complaint and raised request again..this went 6-7 times and seller kept rejecting my request despite the fact that i kept mentioning this to customer service...later they blocked my account and now i can't access my account and they are not opening it or responding my mails and customer service keep saying that please wait this time it'll open and by far I've called them 17-18 times but i get same response and no results
