Dissatisfied customer!!

I have had endless trouble with the vehicle i bought last year!! I have just had to pay close to R40 000 for a Cylinder Head Gasket, new cambelt, thermostat, Coolant bottle, radiator, upper & lower Radiator hoses, fan belts and water pump excluding any labour costs.... plus previously buying a new boot lock and paying for fitment. Not to mention taking it back several times for the hand break light showing constantly on the dashboard (which was never sorted out) The company I took it to for repairs now, have seen that previous work was done on the engine for the same issues I had and some of the pipes were glued together..... How is a vehicle sold with out having a complete check of the engine being done, before selling ANY vehicle. Being stranded on the side of the highway with my daughter is not the way I wanted to spend my festive season!! I am totally disappointed with the vehicle I purchased.
