I sent an item on 13/01 with Royal Mail.
It was the signed for service as it was a £45 item.
I checked the tracking on yesterday and it showed as being delivered on 16/01 - with a signature.
The signature, although illegible, had the name of the customer printed beneath.
Today the customer has been in touch to ask if I have a tracking number for the parcel as it hasn’t arrived yet!
Not really sure whaf to do.
