Hi Anand,
I am sorry to hear that you are having trouble with your eBay transaction.
There are two ways to close a dispute; one is with mutual agreement with your seller. However, if your seller is not cooperating with you, you have the option to file for buyer protection. As you might be aware, buyer protection covers your eBay transactions up to 10,000. You may find a step by step instruction on buyer protection here: http://pages.ebay.in/help/tp/esppp-coverage-eligibility.html
Also, if you have paid by your credit card, you may lodge a complaint with them.
I hope this helps!
Regards,
Sapana
