Can any one tell me what to do when a mot tester brakes the hand brake have reported to vosa and others?

I would think the tester has not mean to damage your hand brake and perhaps broke when he tested it you are perhaps fortunate it didn't go parked on a hill or when you needed it in an emergency situation.If you have reported him then you will have to wait for an independent tester to see if the hand brake failed through miss use or was faulty before you took it in for test this is reason we have a test every year
