no response for over a month

after a battle of over a month discovery have not given me any feedback and i really find it disturbing that i have to be a member of their medical aid, i want someone to call me about this and soon too, discovery want me to pay a fee now to reverse the payment they paid into a wrong account so i have to pay for their mistakes, i wish they could just take accountability for their mistakes, its been more than a month and no email no call nothing i expect someone in finance to contact me by the end of the day i really feel like going with all the data to news24 and show the whole south africa how pathetic discovery customer service is,
