I've finally bought a pair of Kef C85, however, on 1 speaker box, a plastic mount plate where the 2 binding posts were inserted and fixed was broken. I have tried to find a place to buy one to replace it, but I could find nothing. I contacted Kef, they suggested me to contact Kef in Berlin, I sent 2 times my requests to this address without any reply.

Can anyone know how can I buy this thing? Thank you so much in advance.
