Group life insurance & Rude staff

So I took out an insurance for my grand mother with Old Mutual, I think about plus minus 2 years ago. So I am calling Old Mutual because I recently found out most of my siblings also took out the insurance for Grand ma with Old Mutual. I am calling to find out the maximum amount you can cover a life and I spoke to Noloyiso that didnt know and transferred me Diyatile who told me it’s up to 100 000 per life. So I am asking then what happens to the other people that also been paying for all this time, she is telling to just continue paying and that can only been look at during claim process. I am calling prior so that I know if I don’t have the policy. Diyatile is rude and not even waiting for me to finish the question she talks over me. She is rude. When I ask her to put me through to someone else, she refused. I got out of that call still not knowing what’s going to happen to me. Very Disappointed, takes me back when Old Mutual was trending because of this fami**** query and yet I might get the same. Calling to find out and wanting to prevent that did help, all you get is rude person that will put you in even more stress while having a sick Ma.
