Thank you for your input.
As far as we are aware we are acting within Amazons marketplace returns policies, and always have.
just say Amazon Terms only offer a pre-paid return postage label
Amazon don't always offer automated return parcels for large appliances which is more often than not the case in the category of goods we sell in, in this case, the appliances dimensions were within Amazons limits, and the return label was offered by Amazon with Evri. We however, don't use Evri, and if we are to book in a collection with a courier service we would use one that we are familiar with, as they are a) much quicker, and b) result in a much lower damage on delivery than other options. Not to say that labels generated by Amazon via Evri are overruled by our courier option, as most will be happy to drop the box off at an access point, and we have had successful returns this way, albeit slightly delayed. We would only rebook collections using our courier if prompted to collect by the buyer, we always offer more than one return method and include a link to Amazons return policies.
We are well within our right to deduct our cost, which is £15 (sometimes £50 for 2 man items in excess of 1.3m in length), from the refund to cover the standard costs of collection (and return postage) from the item, again, this is not with Evri, this is with our own choice of courier.
The buyer is free to act as they please of course, however we are not to foot the bill for carelessness in the case of buyers remorse, especially when the dimensions of the appliance are on the listing in multiple places, measured to the millimetre, if it were a pair of socks that weighed in at about 100 grams, sure, £15 is overkill, however a near 30kg hunk of metal in a box is not cheap to transport, no matter how you look at it.
We always provide the proof of dimensions in A-Z logs, however this does not always tip the scales in favour.
