Flipkart Internet Pvt Ltd - Unable to return faulty product

I had placed an order of Ceiling fan of Rs.**** on **.**.**** which was delivered to me on **.**.****. When i assembled fan and tried to turn it on. It started making noise and I can seen wobbling. I immediately requested for return due that reason. But instead of accepting my return request they blocked my account by saying you have returned too many items. Same thing have been done by them few months ago and I had to bear the cost of that product. I couldn't afford everytime to pay for their defective products.
