Poor Service

I'm attempting to add a dependent on my medical aid who has existing membership with Discovery. I've logged this query with Discovery. Firstly, they've tried calling me during working hours and unfortunately I missed their calls on two occasions, shortly after the first call I requested a call back via email, but email responses where only received a day or two later. My initial request was sent on the 3rd of Feb and is still not resolved. Secondly, I was told over email that I should complete forms for this dependent although she is already a discovery member. I've been told that this is necessary for audit purposes which is baffling as they would already have a completed form for her when she initially app**** for membership in her name. I'm sure email- or telephonic correspondence from me should be sufficient for audit evidence to add her as a dependent. Poor service in my view on two different fronts. If this query isn't resolved in due course I might reconsider my membership with this medical aid.
