Having been a Marketplace Seller on Amazon for over a decade, I've just received my first ever A-Z claim. The item I dispatched had a delivery window of (quoting the Amazon order page) "Mon, 23 Feb 2026 GMT to Thu, 5 Mar 2026 GMT". At 08:43 on the morning of Monday 23rd Feb the buyer messaged me "never came refund me" - an order rather than a request. I replied asking that the buyer wait until 5 March to allow Royal Mail time to deliver, but received an A-Z claim the next day, which was forthwith granted by Amazon. I messaged Amazon, asking why they seem to have no respect for their own stated delivery parameters, only to get the usual meaningless rubbish back from them. I very much doubt that a reasonable person would demand a refund then launch an A-Z at the very start of Amazon's stated delivery window - this is a scammer. So, AMAZON REPRESENTATIVES OUT THERE, what have you got to say about the utter contempt in which the company holds both its marketplace sellers and its own advisory on deliveries? This item was not particularly high value, but this experience has nonethless left a sour taste.
