Service bad!!!!! Communication bad!!! No technical advice nothing!!!

So disappointed in Mercedes Benz Wonderboom dealership. Should have listen to my gut feelings. My car never gave me problems , now that it’s from there it has major things. The customer service is bad. No technician talks to you or advice. They allocate everything to a booking agent. Collected my car yesterday after weeks and weeks , no technician has spoken to me or checked up on me. I’m so disappointed , the service was bad!!!!!!! After collecting the car I still have to focus on it again after they kept it for long. They took advantage that I’m a woman I don’t know anything, but that shouldn’t be the case. This is my car and I’m entitled to know. I’ve been driving for years and had many cars. Never experienced such service and no communication from a dealership. I believe in thorough work!!!! And going over board. Then leaving other things without explaining !!!!! What if those things affect my car!!!!! And I don’t need to drive it, why not advise on service and I’ll pay for it??????? Nothing was just left the way it is!!!!!
