I bought a 16 gb pendrive from ebay on a flash sale at a very discounted rate. it was okay at first I paid for my pendrive through debit card at the time of payment delivery of product was available at my location . I was supposed to get the product within a week but after some days I received a mail that the product is not available at your location.
If it was not available then they should have told me at the first place and after several emails my problem got unnoticed and I never received my money back the website was blaming the dealer and the dealer was blaming the website.
