RE: RPM MODELTECH
So, he shipped it to you then. I take it you haven't received it? You're in Spain too. I wouldn't ship to Spain via the postal service under ANY circumstances. Have you put a claim in? If so, it can take several months for the claim to be settled. I can't see how you can blame the supplier, you've run the parcel through two completely different postal services, just asking for trouble.
I guess the cheaper postal system, rather than UPS or Fedex, was a false economy eh! Good luck with the claims!
