Terrible service

My son's car was booked in renew-it Sandton on the 19th April with the recommendation from the insurance. When they did the repairs upon collection on the 05th May he realized that the head xenon lights had been removed. They were called and notified immediately, since then he has been sent from pillar to post. It's some people are not in the office, or Sofleen will ask Camilla to call back, then when my son kept on calling he was told Camilla was on leave and nothing could be done in her absence. Today 01 July 2021 I called, transferred to Soflleen and apparently she was not in the office.. Was transferred to Camilla and when the returned to reception I was then told that Camilla could not take my call as she was busy with a client, as if I am not 1, the reception decided to cut off the call on my ear. I have requested for them to call me that was at 15:25 up until now there has been any reply.
