Bad customer service

I Captain Sihle Mbewu wishes to express my disappointment and dissatisfaction for the kind of service I recieved from a service advisor (Shae Naidoo) attached to CFAO MOBILITY TOYOTA EAST LONDON.

On the day in question, I instructed my driver to bring in a Toyota Hilux GD-6 RB with registration number (KRW 770 EC) for a service. Upon service inspection,I was informed that there's a missing nut in each wheel, I acknowledge that and I further indicated that there were previously LOCK NUTS in those empty holes and I would like (SHAE NAIDOO) the service advisor to kindly ensure that the missing LOCK NUTS are replaced, of which we were in agreement. I later learned that they replaced the missing LOCK NUTS with normal Studs instead of LOCK NUTS as instructed. I immediately made contact with (SHAE NAIDOO) while the vehicle was still in the premises and expressed my concern. Unfortunately (SHAE NAIDOO) became aggressive over the phone and started yelling at me, informing me that they do not have LOCK NUTS in stock, this basically means that I paid for something that I didn't ask for. I believe there's a vast difference between a LOCK NUT and a normal wheel stud. I extremely hurt and disappointed by how (SHAE NAIDOO) handled my situation and couldn't offer any assistance besides being rude and speaking over her voice.
