Recently I was searching for a pair of shoes in amazon and I found a combo of four pair of shoes. I thought thats amazing offer I should order, So after taking a close view of all tha pairs of shoes I decided to buy that product.So I ordered that combo pairs of shoesin CASH ON DELIVERY mode of payment. Than a message I got that : - your order is booked successfully and will be delivered soon.After some days, the product get delivered. I was really excited to open the parcel. When I opened the parcel I found that there are only three pair of shoes instead of four! .Same type of problem was faced by my friend who ordered the same combo! Unbelievable but true.So I immediately called the customer executive, She told ok sir sorry for the mistake make the package ready our courier partner will take it back from you. Then I asked for refund so she said that that combo was not Amazon assured so the seller ( Third party ) will refund you in your bank directly. So I followed the procedure to get my refund.It was justttttt hectic! The procedure of refund should be easy.but rest of the amazon services is good.This was my experience.If something like this happened to you then write down in comments.
