I have booked product from Amazon ( #[protected] on 24.02.17. But product never reached. Even tracking i.d. provided to me was fake. Now they are saying we have refunded your money on 15.03.17. And provided me a transaction no. But till 25.03.17. No money has reached. I think that no. is also fake. They are saying you contact bank(BOB). which I also did. But they could not also find anything.
Now they are emailing/saying. It is between you and bank. We can not do anything. Pls. help to get my money back
