Engine light went on

Morning<br> <br> I took my car for 120 000 on the15th of this month and later when I go the car not even an hour later it started making this noise and the engine light went on and I didn't know what was going on. Took it back and then they called an emergency guys to come and look at it as all the mechanic have already gone home. He charged something from it and the engine light went off and the noise was back to normal. On the 21st it started again and on Friday I called the emergency line and the guy that I spoke to said I should bring it so that hey can see what is wrong with it and you know I didn't have a problem with that but my problem is that I leave in Middelburg Mpumalanga. In the morning of Saturday 23rd took it in but I called them and I spoke to Jimmy and said I should bring in the car so that they can see what is the problem. Got there and they looked at it and did what ever they did but said to me that if it happens again I should give him a call so that they can make a plan. I took the car and went home in Middelburg and when I got there the engine light when on again I called Jimmy to let him know he said he will get back to me and I am still waiting even now. Need help
