Bosch is useless and should not be trusted whatsoever

My vehicle was driven to Bosch in Benoni for a service in June 2023. After they serviced my vehicle they were unable to start it. I was told that the engine has seized. They therefore gave the vehicle to Nige Auto which is next to them to open us the engine and to fix it as they are completely ***********. The vehicle has no problem at all as it was driven to Bosch for the service. The vehicle is being used for business purposes and till date which is the 2nd of october 2023 and till now i have not yet received my vehicle. They are completely *********** and greedy. They don’t take responsibility for their actions and now other people must suffer due to them. I am renting trucks on a daily basis because i still need to receive my vehicle from them as i have been waiting 4 months for my vehicle.
