Wrong wheel cap after Service was done.

Returned my car for a rear brake adjustment after a service. Upon return, a wrong wheel cap was on the particular wheel they adjusted. We notified them the same afternoon and they said they will look for it, we must just bring the car to the shop the next morning again. NO wheel cap. They took another wheel cap to go and look for the exact same second hand. They now have 2 of my caps.<br> <br> Phoned repeatedly and was continuously assured that they will get one. Spoke to the same lady Danielle every time. She did give it to the technician and then to their driver to get was the answer and that it is the technician that has to pay. In the meantime, NO wheel caps. This all happened in April already. Went back there this week and the same lady again assured me that she will phone me on Thursday. No call! Went in today again and the same lady could not recall my face. Empty promises! Eventually managed to speak to the manager Carlo which in return even asked the same lady to remind him to phone me!! Seriously!! I tried to phone Bosch Car Service Customer Care centre to lodge a complaint and I was put through to an answering machine where I had to leave a message. <br> <br>
