After a bit of advice. Have a bit of a problem where I purchased some goods on Amazon from a business seller. I received the items the other day, but on opening the packaging - the item model is wrong. The items are not suitable for me at all. Now the seller's been quite good, and said that they will offer me a partial refund if I want to keep the goods, or said that they will arrange for a courier to come and pick the goods up, and offer me a refund. First time I've had a problem but I'm obviously concerned in case the courier picks the goods up, and seller claims they've not arrive or something? I'm assuming if I get some paperwork from the courier to say they've picked the items up this will be fine and if problems I can claim through Amazon still? Or not? I contacted Amazon who've told me that firstly, they wont get involved unless a case is opened, and also that the seller is under no obligation to provide me with return costs if I arrange for my own courier. Goods are over 20kg so concerned about the costs of doing that anyway.
