Very disappointed

Towards the end of June my car had a pop up message 'consult workshop without changing gears' and couldn't start. I towed the car to Maritime and I was told is because rats had damaged the cars wires. That was fixed for 25K and took the car. After 8 days or so driving the car the pop message shows up again and i towed the car to Maritime. I was then told that the car has a gearbox lever problem that will cost R156 000 and it's above what the car is worth. We then at home decided to tow the car back home that costed 19k to Margate City motors and we were told that the problem is the battery which costed 5K. We waisted close to 45K for something that is 5K. Am even sceptical about taking the car to PE because of the emotional damaged caused and the fact that I don't trust Maritime will help me if I can have another problem with the car. To say am disappointed is the least and if a negative review was allowed I would give them that.
