I bought an item from amazon market seller and the item is faulty. The seller has organized a courier to pick up the item and have it shipped back to them. I have been sent a returns label, and have become a little weary. Should enclose any paperwork and should i ask for a receipt from the courier
Yes but this is not Amazon, it is a market seller. I would print another copy of the return note and get a signature from the courier. No harm done but it does cover the possibility of the courier misplacing it.
Amazon is usually very good at refunds even from sellers on the site.
For returning having a receipt from the courier will speed up the process should things go awry. Also if possible take a picture of the item as proof that it was handed over in perfect condition.
I have had two instances myself in all my years using Amazon where sellers didn't deliver (quite literally nothing showed up). In both instances Amazon refunded me and I was able to buy from another vendor on there and get my product.
