Extremely BAD SERVICE

My Toyota corolla was towed twice to McCarthy Bruma because it had a RED ENGEN light on and couldn’t accelerate or move, but could start. It has been there for over 2 weeks going for the 3rd week tomorrow. I have been told tooo many stories that I actually don’t know what is wrong anymore. 1st being computer box, something cracked in the ENGEN…etc…then I was told that the IC was taken to another place for repairs on Thursday I was told that it has arrived and will be fitted in the car. Thursday 16h00 I was told they have run out of time it will be done today. Today upon calling…apparently it couldn’t be fixed at the other place and has been taken to another place, but back in the service garage, the consultant will call me shortly. I know I will have to call again 16h30 to check on the progress. Bearing in mind that I am SELFEMPLOYED, I mentioned this to them. I have NEVER been phoned, I am the one who keeps on calling them daily (I have proof on my March statement)… and depend on my car to do my jobs. I don’t know if they are able to fix the car or if am taken as WOMAN who can be taken advantage of daily - who needs to make a plan. I guess now they’re JUST keeping my car there to fix it when it suits them and push other simple jobs and get paid. People I have HAD it, if you cannot FIX please just tell me I will find another TOYOTA SERVICE STATION WHO CAN DO THEIR JOB THAN KEEP CLIENTS CARS FOR NO LOGICAL REASON!!!! I DON’T THINK A MECHANIC WHO WORKS ANYWHERE OR AROUND THE CORNER COULD HAVE GIVEN ME THIS KIND OF BAD SERVICE.!!!!
