Bosch desaster service

On 12th December I took my car for a service at bosch randburg. I wanted a full service which they ended changing other things which they said needed to be fixed.I paid them R17190. 00To my surprise the car came back overheating, smoking, shaking, hooter and wipes not working and the oil was mixed with water, I took it back on the 17th Dec 2019 then they told me the head gasket blown, the radiator is liking and that I must pay R3306 to assess the car. I had to tow my car from bosch car service to another technician who fixed my car. If u love your car, don't take it there
