Appologies you are right that number was not the tracking number, PM3408703, was just my invoice ref... but that was not what they first called it.
Anyway when I went to complain to them I found I needed an extra code on the end, I dont know where I was suposed to get it, but it appeared as a reference on the complaint form, so it was a bit of a lucky find, sorry again my friend.
The cprrect tracking number is;
PM_2622583_3408703
