Poor service, I mean no service, from Discovery call centre

Absolutely shocking service via the call center!! I am actually speechless. I have the Discovery app on my phone and I have scrutinized the website to try and ascertain a network GP in the area we have moved to without success, it is not user friendly at all. As a last resort I called the call center and was asked security questions despite having entered all the relevant details via the IVR. I "failed" the security question re whether my husband (the main member) has an active debit order to pay our membership, despite stating that we are prescribed to Discovery via his work and I am assuming it goes from his salary?? Following this the agent refused to assist me with where I can find a network GP!!! Surely giving information re a network GP is not classified secret information for which you should pass a special test???? I could understand if I was requesting banking detail changes or if I wanted a special authorisation that could be viewed as a risk, but surely assisting a member as to how to access services for which premiums are collected monthly should not be so difficult
