Bad management

I am very disappointed to share that we have more than ones had such terrible service. MO ey hungry people. No care for people. First I was in hospital last year with heart condition and has a heart monitor on to test my heart rate. They come and give me a bill 9pm at night and want to force me to pay no matter how many times I told them my medical scheme will pay! Anyway eventuallh they backed off. And now this year in August I. 19th my son was admitted in day clinic, the Dr didn't even explain to me tests will be done. We had to pay everything cash and so before we left the hospital I got a call already to go pay R760 i know how they are so went and paid and even made sure later that week I owed nothing. They assured me and even sent inv showinv R0 then week later I get an Sms saying I owe them another R860. So when I phoned the guy was so rude and just says there was more tests, I asked to be put through to his superior and he put the phone down in my ear. I then figured out on my own that the one bill was charged to my ID and one to my sons ID and that's why it didn't add up so to me this is bad management and caused unnecessary extra stress in a already stressful time for my family as our hospital bill was already 14500....
