It turns out the last location it was tracked at was about 50 miles away from the deilvery address and it was signed for by someone other than the addressee.
Was this verbal or in writing?
I know it could be throwing good money after bad but if it was me I'd take this up as a matter of principle. When does RM's duty of care end though (at the border)?
Inform your contact at the RM that you will be forwarding all information onto:
and that you will be writing to his MD (recorded)…!
..and you will also be progressing with a claim in the small claims court unless theres is a satisfactory conclusion.
Although different to your situation my own claim for lost Fox 36's went on for almost 3months.
