I was actually happy with the product (Jabra Move wireless headphones), but after 6 months one of the ear pieces broke from the frame, the connections are very tiny. I contacted amazon for a replacement and they refused despite the product being in stock. It was and is the exact same product but with a different stocking code (ASIN) but now a different price, as I bought it during a discounted period and now the price is back to the original.
Amazon refused to replace it because of this ASIN code (despite the customer service team member confirming it was the same product), apparently it's impossible, but no reason was given as to why. If I wanted to replace them I would have pay for my return packaging, and then get my refund and pay the difference to replace them. Even though it's the same product I can't even write a review on that product to warn people about potentially not being entitled to a replacement for a faulty product. It's very very sneaky behaviour and becoming more and more common.
Amazon is all good when you get your little discount but my experiences when something goes wrong now are that's it's not worth the hassle.
