Poor client service: Non-response by Bestmed Call Center

I am a member of BestMed for a long time. I have been trying make to make a simple inquiry regarding removing an additional member from my account for the past 3 days. I tried calling the call center several times since and was put on hold for more than an hour at a time until I gave up. I emailed the service desk at BestMed with my inquiry but there was no response either. Just an automated one....I pay over R4000 per month in medical aid fees and I am extremely disappointed. I hope someone at BestMed can reach out to me to assist me with my inquiry. I am desperate now as this matter is urgent.
