Bad service since I joined

Good day, <br> <br> Please advise on how do I go about cancelling my medical aid membership with you. <br> <br> I am having no joy dealing with you. I called to find out why my debit order has not gone through because I am no longer employed to the company that used to pay part of my medical aid and honestly, I was told to call them (previous employer) and find out from them. <br> <br> I need to update the information on your side so its debited on my account like before and I got no assistance. <br> <br> Requested a simple check to see if all debit orders went through and nothing's outstanding-still no help. <br> <br> I am still awaiting my card which was to be couriered to me in 5 days from last year November, still-nothing. <br> <br> Requested my membership details as I am unable to see a doctor -nothing still. <br> <br> Please understand my concerns and assist where possible. I am already in talks with other medical aid companies. <br> <br> I am disappointed and appalled by your poor service.
