Bad service

the service of Keyhealth medical aid is so terrible I don't know where to start, to write an email for management's attention is also no good as it ends up with the normal consultants who think they can tell you what they think. they also claim on their website that they will respond within 48 hours, what a lie. I am waiting now for close to six months for them to respond to my mails, every time you sent a mail you get an automated response of "we will get back to you shortly" what does this mean as they never respond to that mail. to call the call centre is even worse because you don't get the same person everytime
