Flipkart — I feel cheated

Purchased 32" LED TV, seller Oscar limited on 12 August, 16.Delivered on 22 August. Within 48 hours as promised the seller did not install the TV. Contacted flipkart there after & their technician came to install the TV on 25th. In the packing no warranty card was found. The has no serial no. & No where on the TV or packing it is written which company is manufacturing / marketing the item.Received by mail an invoice copy which has no ref. No & clearly written that it is not a vat paid invoice. It does not contain the item's serial no. After installation the TV found to be faulty by the technician. No where on the manual supplied it is mentioned that it is the manual of that item & no company, s name. We informed flipkart all this & wanted a return & refund. It highly violates selling contract. But still as on date 29th flipkart has not confirmed return or refund. It is a serious breach of contract of sale but till date it seems action or no action taken by flipkart raises suspicious question in mind. The seller should be immediately blacklisted & my money refunded.
