Bonitas demand a payment where the error was not my fault

I was requested to draw blood a chronic illness. I went to the doctor for that. I went to Dis-Chem and I was told my results were not received then I went to the doctor and I was informed the blood drew was not enough. So my question is if the Lab did not do the right thing why am I to pay for someone else??? This medical aid is treating me unfairly because I'm a BonCap customer with a low income earner. I feel emotional abused by this company. I'm so disappointed. Coming to think about it I grew up under this medical aid as my father was and is still using it but my experience is so terrible I'm even thing to change it somewhere else.
