Bad service at seamens renault port elizabeth branch

I took my car for service on the 19th of September for the first service at 8500km, the car did not have any problems. On the 7th October the car did not want to start flashing an engine sign on the dashboard, called in the branc, the lady I spoke to said I should tow the car in at my expense, on Monday I called my insurance which gave the number for renault roadside assistance, they assisted and towed the car to North end, I called in to ask if I needed to come, spoke to Megan she said mno, I must put the warranty booklet in the car, later on 11h15 they called again to say I need to come and sign they will not work on the car, I came. I asked how long will it take for the car to be fixed, they could not give me an answer, went to the branch manager who was very rude and undermining me as a female, said he did not know anything about service dept, asked toilet a call and ask them how long the car will take, he told me that when u are sick u don't go to the vet but to the doctor so he won't help me I must wait as there are car's booked in for service. I asked him why he is shouting at me when I'm not shouting, he said sorry with a rude tone, we argued over him shouting at me again, he ended up saying my car will not be serviced at his branch I need to take the car. Port elizabeth branch need service dept is horrible, they messed up my car during service and now I need to wait for the car's booked in, still they don't have time frame of waiting times, and when I took the car for service I was no.3 and got the car at 17h30 after calling them, they did not feel like updating me.
