REFUND DISASTER AND INCOMPETENCE!

I have been a member of Discovery Health through my previous employer. I resigned and left the employment end Feb 2020. I changed my contributions to my personal capacity through an agent from Discovery. At the end of March I found out I was never covered even though I made EFT on 2 April from my personal account as per consultants request. I queried it and requested a refund on 7 April as I never had cover. Discovery then told me they refunded my previous employer....which after investigating was a lie. I sent them my proof of payment as well as new details with existing banking details AS PER APPLICATION FORM. They told me week of 1st June 2020 they will refund me. They sent me an email to confirm bank details - banking details that was used in 2012. They asked me to confirm before they will make payment. I had to send proof of bank account too.... I rep**** and told them the bank details were INCORRECT. I completed banking details form and sent them proof of bank account that I currently use and submitted on my initial application....THEY PAID THE REFUND INTO THE 2012 ACCOUNT WHICH I DID NOT CONFIRM AS BEING CORRECT. I TOLD THEM NUMEROUS TIMES IT WAS INCORRECT AND THEY RECEIVED MY PAPERWORK. I EVEN HAD A CONSULTANT PHONE TO CONFIRM. What the hell Discovery???? I needcthe money to be reversed and refunded to my CORRECT banking details. It is two months now since my request...
