Here are some update on my issue with eBay. 

I filed dispute with my credit card and after 3 months I won the case and got my money back. 

 

Lesson learnt:

- If you have problem with any credit card purchase online, file dispute with your credit card issuing bank.

- eBay and Paypal works together. So, if your case is declined by eBay, Paypal does not allow you to file dispute.

- Never trust eBay

- Never believe eBay buyer protection program. It is bias program.
