Bonitas the worst service ever!!!!!!!!!!!

Good morning. I have never experience such a bad useless service like with Bonitas. I have changed my banking details with Bonitas. Unfortunately I have done it after the debit order running date. So I have followed up that the new banking details is on my profile and they have confirmed that it has been changed on their side and a double instalment will go down. only then they will lift the termination on my medical aid. Only to find out on the 1st of June Bonitas again have debited from the old banking details. So when I phoned them to find out what the problem is the urgent lady said to me "its because you don't have enough funds in your account" Me trying to explain to her that I have more that enough in my account for the double payment. Still she argue with me and said I don't have enough and I must follow up with my bank. In the same time I follow up that they have the right new banking details. It showed that Bonitas tried to debit my monthly instalment from the old banking details. After I have sent all my proof to Bonitas they realized that Kgomotso Dipholo who have changed the banking details did not change the termination date of the old banking details on her side, the termination date of the old banking details is the 9th of September 2021. So Bonitas said no they will fix this and get back to me. This was Friday the 4th. and today is the 6th of June and still nothing has been done no one even tried calling me to say sorry there is a delay. Every day when I phone it is the same story. Mam we have logged it and it will be sorted today. This is the words service ever. And when I ask them about debit order bouncing back banking fees I have to pay for their mistake all they can say is oh sorry mam. My daughter is sick and what do they tell me when i ask them to lift the suspension so that i can take my daughter to the doctor. No mam we need payment first but who's fault was it to start with? Again they said no mam we logged the issue with financial department they will sort it out and then we will arrange for a special debit order for you. I am so over this issue. Worst service ever. I am thinking of canceling my medical aid from Bonitas and get another provider.
