I suspect they change their machanic because before everything was perfect

On the 25 of June 2024. I have send my Mercedes Bendz c220 cdi for minor service . In the afternoon when I go to collect my car I have found that the car is no longer starting. I have tried to complain to head office but I didn’t get help. Am just giving a warning to people who are still planning to send their car to ormonde that be careful because they can also damage ur car like they did to mine
