Dear sir mam flipkart blocked my account by giving reason of returning a lot by me and till date they didn't give me valid reason for that sir i was their valuable member and i ordered more than 200 items and have returned maximum 20 This is high return sir please help me. I did the last return one item was missing I ordered 2 sets of overlock but they gave me only one. When I put return, they canceled my request and after a lot of effort, they returned my money. After 1 week they blocked my account. After blocking they delivered my 2 items so I refused to receive them because they blocked my account so how do I receive them?
