Very sad and scared my parcel is gone forever

Tried phoning the help line to trace my package but no one answers the line. I unfortunately kost my tracking number but I can give all of the other information. Address, phone numbers, details of person sending it, details of person receiving it but no one answers the help line. This is an extremely special parcel going from Scotland to Amsterdam and it was handed in at the post office on 15 June 2024 and the recipient has not received it yet.
