and i want to refund some back to the buyer. however.
the post office has given me three proof of posting receipts with no bloody prices of the postage on, and as i posted three parcels together, i have no way of working out which was the one i overcharged on. is there any way of finding out from the proof of posting labels? items werent that expensive, but i am worried about charging too much and people complaining. is there anything i can do?
