Bikers Warehouse caused serious damage to motorbike they where unable to repair

I had the most unpleasant experience servicing my motorbike at Bikers Warehouse. After taking more than two weeks, they informed me that they could not fix the problem and that I should collect the bike. I took it to another person (not even a mechanic) to look at who fixed the problem, which turned out to be a small issue, in under 10 minutes. However the person showed me that Bikers Warehouse had in a "spay and pray" approach stripped a bunch of wiring, shorted it out, and in the process blown the ECU (an expensive and difficult to replace item). In trying to resolve this have left numerous messages for Mike Puzey the owner, who refuses to return my call.
