If the seller has received their item they should cancel the order citing ' Problem with Buyer's Address' this will fully refund you, and it will not impact on their seller performance.
They can then relist the item for you to buy again.
I would strongly suggest if you do buy this item or any other, not to use Click and Collect as this is causing the issue, but to ensure your delivery address is correct which is showing on the left hand side when you pay at eBay checkout.
