Broken & Crack of Windscreen on premises of Lexus Lynwood while car is being repaired and washed

On the 3rd of September 2019 my car was taken to Lexus Lynnwood for a right drive shaft repair of the back wheel. Pieter Wouter Kriel was my adviser on the day. The repairs was approximately R8300,00. After the repairs was completed it was requested by Pieter Wouter Kriel if my car could be washed it was agreed that the car was be washed. After this process was completed my car key was handed to me as the repairs and wash has been completed. as my wife and I got into the car to return home we noticed that the front window was cracked from the bottom of the passenger side up towards the middle spreading towards the driver side. As we noticed the crack Pieter Wouter Kriel was call to inform him of what had happened as the window had no cracks before any of the work/wash was done on the car. I informed Pieter Wouter Kriel that due to this happening on their premises they have to repair the broken window. I have contacted Pieter Wouter Kriel after returning from my leave. I have contacted Kano at the headoffice as no feedback was received from Pieter Wouter Kriel. It has been more than 30 days and I have received no further feedback from Lexus on when the repairs of my window will be done. I now have to carry the cost with my insurance to replace the window.

This in my opinion is very bad service on their part, lacking in communication. Due to the damage happening on my car in their care and on their premises they should be held responsible.
