[Resolved]  Flipkart — no return despite sending a wrong battery

I placed an order for samsung galaxy tab battery t231. Instead of that the seller shipped me a different battery of another model. My order no is id od[protected]. The battery was delivered on 24 oct. I immediately raised a return and refund request, which was accepted and i went ahead to book another battery from another seller (Which was delivered before time and is running well). On 26 oct, without giving any reason, the return request was cancelled. The customer care was of no help in determining, why it was cancelled, however he helped me raise another return request. A person from e cart (Flipkart calls them wishmaster) arrived on 28 oct and refused to take the battery back, as it was not sane as what was shown on the flipkart website, from where the battery was ordered, i tried hard to explain it to him, that if it would have been the same battery, i would not return it. The return request was raised as the model of the battery was different.. He kept insisting on the same battery and finally left. Flipkart customer cate again assured me that the battery would be taken back, as in their records the return request was still active, two hours after i spoke to the customer rep, the return request was cancelled second time.
Customer care again assured me that the battery would be picked up and sized another return request. I got a sms that the wishmaster would pick up the battery on 04 nov, however, on 30 oct, i got another sms, asking me to keep the battery ready as the wishmaster would pick it up by 2100 hrs (9 pm). At 1830 hrs, again without any reason or communication flipkart cancelled the rerun and refund request.
Customer care now for the fourth time has taken a return request, which would now be verified and then only processed. The end result is that the battery is still with me.. And my money has not been refunded.
On three occasions, i have been told that the complaint has been escalated, however on ground no one has inquired and every time i call customer care, the clueless customer care rep, just gives me some cock and bull story, which keeps contradicting the one given to me earlier or with facts on ground...

It seems that i have given a forced donation to flipkart on diwali
