I assume after cut-off on Friday, so had to be shipped by Monday.
So, what did you do?
As far as I was aware shipping has to happen using Buy Shipping, so Royal Mail, DPD and Amazon Logistics (although today most will not work with RM and I am sure we will all have lots of issues as Amazon’s fault, but we are of course to blame!).
Shipping to another address is definately not allowed as others have said.
If you cancel as others have suggested, that will count against you, unless the Buyer cancels, not just ticking the address issue box, otherwise we might as well always say that excuse.
If you cancelled, I would suggest to contact Performance to let them know and why.
They want screenshots always as proof. Links and time/dates of any emails etc.
I was told by SS before for SFP order that asked to alter an address: You could always send the receipt using Buy Shipping to the address on the order, then once received, so tracks ok and not affecting your metrics, then refund the item. But as I pointed out to them, that will cost £5 to Amazon to process the refund, plus the cost of Buy Shipping.
But, SS saying to send to another address has to be worse.
