Unhappy about the service

I am feeling unhappy with the service that I received so far. They are not making the monthly deduction like they are supposed to (I signed for it in my application form 1 November 2017), so I have to make time to go to the bank and send the proof of payment. At end of November 2017 (after my missed period) I found out I'm pregnant and had to wait for an appointment at the gynecologist, I was 9 weeks. The same day I phoned Bonitas to tell them I'm pregnant and if they will cover my maternity as I was a week and a half pregnant during applying for medical aid. I could not have known by then - I made sure with a home test that revealed NEGATIVE!!! Implantation cannot tell me that I'm pregnant yet! So the lady which I spoke to said to send a doctors letter to tell how far I am and I did. I phoned a few times for a reply which they told me they already rep**** (I still did not receive a reply) and that they are not going to cover my maternity, because I was already pregnant. How can you tell you're pregnant when a test show negative and you're only one week and few days???? They are not even trying to understand, I have told them I'm willing to pay for the few days that I was "pregnant" during application. The 3 months waiting period I understand (I have already paid the waiting period at Bonitas), but it is common sense to know that you cannot pick up you're pregnant at 1 week!
