Policy. Bad service

I opened a kaizer chiefs policy for my brother over ten years ago. Two weeks ago they send me an sms saying the policy is two months behind. It is lockdown and I am currently not working. Today I called them to ask how much I should pay to keep the policy open the consultant very rudely answers me that the policy has lapsed. How come did they not inform me that in the sms when I only know its behind one month? What should I do now since I have paid over ten years on this policy. Very very bad service from Hollard. I am disgusted!!
