Bad service and possible lost item

I wish I could give them -5 stars My parcel *** was booked, paid for and collected on 21 November 2025. I was issued with waybill ***. On 24 November 2025, I received an email to ask the receivers details which I have completed on the booking but I gave it anyways. The parcel is still not delivered. When tracking and calling to follow up, that waybill number does not exist. It is a very expensive item and no one is getting back to me with any feedback.
