Had a look into it. Not UPS's fault, although thy are trying to help more than Thomann. Thomann dropped the ball when they exported it back to themselves for repair. The correct bit of paperwork and none of this would have happened. I can try and claim back from HMRC but in reality this will just be a bit of an expensive lesson. Good news for the British economy though, my chronic GAS and the money that goes with it will be going to my excellent local shop A-Strings and Andertons from now on.
