Hyundai Kempton (Airport) bad service

I took my vehicle in for 60 000km service, at Hyundai Airport Kempton Park branch, when I collected my car, it started, but once I left and made a stop my car died completely, after wiggling some plugs in the engine (yes I am a women and know nothing about cars) I got it to start. Anyway today on my way to work this morning, while driving, my car cuts out, so I have to pull over. I called Hyunday a couple of times, before I eventually got a call back from Philemon?, who sounded annoyed that I called and bothered him. After a further wait alongside the road, I got a call from the service manager who advised that they would sent someone out to assist me. I waited about an hour, which I don't mind, and a mechanic pitched up, and sorted out the problem, a loose wire on the battery. What really annoys me is their aftercare service, no one called to check if I made it to work or to Apologize for the inconvenience caused. I am a single women in my 50's and really did not appreciate my car breaking down after a service done by this branch. My vehicle was fine when I took it in
