Poor service for service providers at Discovery health

Customer care for service providers are atrocious! Service providers are for eg. GPs. I sent all the correct e-mails and attachments to update my details (many times by the way), and still the wrong info would be captured. The excuse is they use Medpages to update details. I attached a screen shot to an e-mail to Discovery as evidence that the details were incorrectly updated from Medpages. I also cannot even complain enough how I struggle to update my banking details. Other medical aids for eg. Bestmed, Keyhealth, Medscheme updated it within 1 day. And they also use Medpages to verify doctors. My question? If I cannot trust any person at Discovery with a simple thing like updating an address how can anyone trust them with their health, money, insurance...Discovery holdings...BIG question mark.
