UK op1 repairs?

hiya,

has anyone got a recommendation for op-1 repairs in the uk?

i dropped mine (a few times) and its (understandably) not turning on or taking a charge - tried sending to Germany as per TE site instructions but the guys there stopped replying and the parcel was returned to me, having not been collected at their end.

So, any help would be gratefully snaffled.

Cheers
