It is impossible to get hold of ANYONE at Malcor Medical Aid

It is impossible to get hold of ANYONE at Malcor Medical Aid, I have changed jobs and want to transfer my medical aid from the old company to the new, but I want to know how much I pay for each dependent, and if we are still covered this month because all of a sudden everyone is becoming sick, I tried calling the numbers on the internet and they all say the number you have dialed does not exist, have i been paying almost 10k a month for someone who doesn't exist?? i have sent emails to both email addresses I found and yet no reply at all!!! this is pathetic honestly
