Self — sold me a faulty item and didn't return my money back

Address:

Hyderabad, Andhra Pradesh

I had buy ed an ear piece (make : apple) in Ebay. It is a faulty one. i had raised an claim with 546664 (claim number) in Ebay. They said that i will 110% of the total paid amount in the form of coupon. Case closed on 30th June 2014, said that in 7 to 10 working days i will bet the voucher, but till date i didn't get the money. Every time i used to call to the Ebay customer care but not give an relevant answer. Please file a case against the Ebay so that no one will effect like me.
