Don't take vehicle for services at Bosch Centurion

I took my vehicle to Bosch Centurion 28/04/2015 for a regular service trusting that if I use a know name brand my vehicle will be in good hands. The following day my car break down due to a failure with the cooling system which never used a drop of water before it went for a service. I only got my vehicle back today 7/5/2015. <br> <br> Hardly driving 30km my car breaks down once again this time some oil system which seems like it was not properly tied up when the cooling system was repaired also my car only used oil when it is changed during services. My car which never had any mechanical problems now had 2 major breakdown since it has been to Bosh which is my opinion is due to faulty workmanship.<br> <br> Trying to call the customer care line ***to report this service centre no answer in 3 hours of trying. Trying to send a mail no response. How can a company with such a well know name delivery such poor service.<br> <br> Guys please don't use this service station no one takes responsibility your car will be damaged and you will have no high authority to assist in solving a branding problem.
