Pathetic Unacceptable Service Behavior from Nikon Centurion

I repaired a speedlight with Nikon Centurion (Premium Brand Distributors) and upon repair, I got a first quote which I accepted on 15 April. 9 Days later quote was revised to a higher amount which I accepted. While waiting for parts, over a month the technician called to inform me that the speedlight can't be repaired and I accepted. When I collected the speedlight, it was cracked above the side rubbers and the part was discarded without my consent and knowledge that the part was damaged in their care. This was in late May and on February, I had replaced the two side rubbers and no indication was showing cracks as well as when i submitted the speedlight for repairs for not firing. Sachin Chinnilal damaged my speedlight and is blatantly refusing that he did so. This is evident in two things, 1. I was never quoted for the damaged parts in the first instance and 2. When I collected the speedlight, no one informed me until I had to inspect the speedlight before taking it back that it was cracked and the part discarded. I sent an email to Sachin and his manager, Lourens Erasmus complaining and detailing the events that it cant be and till today, 9 days later, no reply from both technicians and at least to acknowledge my concern. I hope Nikon will not try get away with this by keeping quite the same way the 2 individuals are keeping quite.
