If you cannot prove delivery with a postal tracking number then you must refund the buyer in full. You can use the proof of postage to claim from Royal Mail for the loss.
You are currently trading illegally as you have failed to register as a business seller.

Seller ... do you mean Buyer ?. Small package/parcel Proof of Postage receipts now have a 16 digit number which when entered into the case will confirm doorstep delivery only ... without that postal confirmation you need to refund the buyer through the case.

If you can't prove as delivered then you have to refund, through the case, but if you try claiming on Royal Mail and it shows as delivered then they will not pay out.
