This number is on the parcelforce. Com website.
Click on "Receiving a Parcel" tab, then click on "Pay Custom Charges".
The number is legitimate.
The people who left negative feedback on Whocalled. Co. Uk are wrong.
This number was on a letter I had supposedly from Parcelforce, saying I owed customs charges on a parcel from the Netherlands. I'm not expecting it so I checked Parcelforce website. The tracking number is genuine, probably from someone else's parcel. It all looks scarily convincing until I checked the phone number given. Both this site and whocallsme. Com say it's a scam.
