Dr. Margaritov's accounts team

My review is not directed towards Life Health Roseacres, where my son was born. My review/complaint is towards the doctor's offices at Life health, specific this doctor's accounts office/team. My fiance and I were expecting our son mid-January 2019, so beforehand we had been seeing Dr. Beula Green, we received our pre-admission code to follow up with our medical aid before our due date, this was fine, medical aid approved everything under Dr. B. Green. During our monthly checkups, Dr. B. Green informed us that she would be on leave throughout January and a stand-in doctor will attend to us if necessary. Our son arrived earlier than expected, 01/01/19. The now attending Dr. Margaritov delivered our baby boy. AGAIN I have no complaints with Dr. Margaritov, rather his accounts team. Fast forward to 29 August 2019, I get a call from a business - National Debt Collector (NDC) telling me I have not paid my account that is outstanding, I receive an invoice for an amount of R4227.68 that is to be paid by 03/09/19 by 430pm or else I will be handed over to the lawyers. ater consulting my medical aid, which they informed me that Dr. Margaritov's practice is not fully covered due to different rates, a portion was paid by them only and I was liable for the balance. I went to see Dr. Margaritov's office the morning of 03/09/19 to whom I spoke was the receptionist, as the accounts lady is on leave until the 25/09/19. The receptionist informed me that the accounts lady for Dr. Margaritov has tried to contact me on my cell number by sending me SMS's, as well as by sending emails with to fiance's Gmail account for a follow-ups, which I responded with 'I've not received a single SMS, my fiance has not received a single email (even checked her spam/trash folders) , i proceeded to ask, if the accounts lady has not received a response via the two mediums she tried to contact my fiance or me, surely she should have tried calling either of us over the course of the past 8 months, no answer from the receptionist. Due to the lack of proper communication from Dr. Margaritov's accounts team, I have been handed over to the NDC and to avoid being put on the credit blacklist I am forced to accept the current procedure from the NDC to set up a debit order to pay the outstanding fee. My questions are 1. If Dr. B. Green is approved from my medical aid, and she provides a stand-in doctor, that means that that stands in doctor - Dr. Margaritov should be covered as well? It's a like for like replacement, if not we should have been informed by Dr. B. Green and her office? 2. Should Dr. Margaritov's accounts team not have tried harder to contact us sooner? the NDC consultant made sure she got a hold of me on my cell or work number, as I'm a consultant too that is out at clients I am in meetings often and if I'm unable to answer the phone I return the call as was this case with the NDC, which proves that Dr. Margaritov's accounts team did not contact us appropriately in order to avoid this situation I am in.

Either my medical aid - Discovery Health, Dr. B. Green or Dr. Margaritov's accounts team needs to take accountability for this outstanding fee.
