OK, a short interim update.
To their credit, Chain Reaction have responded admirably to this issue. I’m impressed.
The additional customs costs have already been refunded to my credit card
The damaged frame will be picked up from my doorstep by DHL later this week
There are no blue frames in the UK but they have found a black one which they have ordered for me and should ship soon.
I’m promised that everything will run smoothly and that I will be happy!
Totally professional, uncomplicated and satisfactory response. Well done CRC.
