Car Service City Midrand- bad

I had the worst experience with Car Service City Midrand. I took my car in for a major service and it came back with power problems. It was jumpy all of a sudden and they blamed it on me saying that I brought it in like that knowing it’s problems. It moved from bad to worse. The manager didn’t want to help me and kept trying to convince me that I damaged my car on my way to get serviced, said I was negligent to my car and took my complaint lightly based on my appearance. He didn’t even try help me instead he told me to leave. I am done with Car Service City Midrand.
