I regularly send items worldwide by International signed and tracked service.
Now royal mail also offer a tracked service for the same price. Why would anyone pay for just tracked ,when signed and tracked is exactly the same price.
They also state that it is fully tracked all the way. In reality it is tracked until it leaves the UK and after that anything happens from the odd entry for tracking ,to nothing at all . You have to go to the country your sending to`s postal tracking and hope they have scanned it and updated the tracking.
This happens occasionally but often nothing shows up on the tracking. Ive had parcels to the US arrive at the US customs in 1-2 days and then disappear for 3 weeks.
Funnily when you start kicking up a stink they usually miraculously reappear with no explanation of where the parcel has been.
If i use Fedex or UPS , tracking is usually up to date and no problems at all.
