So I received a note today from royal mail saying i have a fee to pay of £3.00 as the sender did not pay full postage? Im confused as to what the parcel is as I dont recall ordering anything that is delivered by royal mail, just the generic asos/ amazon orders are to come soon. Is there any way of finding out where the package has come from or what is is? Theres no tracking number or anything. Its also under my surname which is odd as i have no clue what it could be.
