Disgusting service from Discovery Health!!!

I cancelled my medical aid with Discovery on 31/08/2020 and received a response saying that they would backdate it and that I only had to pay R3812 which was for the medical savings that I had used, which I agreed to, payment was made and an email received from Discovery confirming that they had received the funds and POP. In the interim they keep deducting my monthly subscription from my banking account which I have to keep reversing and this costs me money, Discovery refuse to cancel the debit order on their side. I then called them asking them to cancel the debit order on their side again, but was told I now owe them an additional R953, and that they would now backdate it to July 2020 and the R953 was the MSA amount owed for July 2020, I agreed to pay the R953 over 3 months as I'm unemployed and have been for almost 4 years. Today, 13/01/2021 I received an email from their Debt Administrator Billing Services, Deshnee Naidoo saying that I owe them R4765 and that they want proof that I'm unemployed, 3 months bank statements etc. and that if I don't provide them with this they will put my name on the Credit Bureau. I have been a member for 20 years and this is how they treat their clients. When calling in you have to speak to a different consultant each time as they cannot transfer the call to a Consultant that you have spoken to previously. The service received when cancelling your medical aid is absolutely appalling and I must certainly will never use Discovery for medical aid or any other product they have and I will most certainly not recommend them to anyone. Discovery is just a money hungry company and do not dare or have compassion for their clients.
