ALL MERC SPARES PRETORIA ARE CROOCKS

I bought a Diesel injector pump and a clutch kit from a guy called Francois. Both purchases where suppose to be picked up by my courier but only a clutch kit was sent. The problem started when it was only a clutch kit was given to the courier. Then these guys sent me an incomplete diesel injector pump without a pulley/gear. THEY TOOK OUT THE PART THAT THEY ARE SURE i WILL NOT GET separate from the pump if I had to get it somewhere else. I have spoken to the team leader (Marco) who told me straight that they will not assist me. Then a manager (Shanray) who promised to resolve the issue but he does not answer my calls.
