Royal mail a joke, sent £700+ machined components to an anodisers, Royal mail signed for, 2 weeks later phone the anodisers to see where my components are, “sorry number not recognised”, bit of detective work find out they had gone to the wall about a month previously, got onto royal mail to make a claim for lost goods as they had not gone to where I sent them, we have a signature here for them thats great where are they, we cant tell you all the mail was forwarded to another address and we are not allowed to tell you data protection and all that where it is,we have held up our side of the bargain getting them to the person signed for!!! never saw them again ,had to bite the bullet and remake, vowed never to use them again.
