Sanlam Policies

I'm not happy with the service rendered to me by Sanlam. I have two policies with them that to my knowledge are up to date. Only last month I noticed they didn't debit, I immediately contacted them to check what was the problem cos the previous month they took more than what we agreed upon. To my surprise they tell me that I closed my mother's policy last year already so on their system I have 1 policy with them. What I found strange is that they have been debiting for 2 policies all this time. I'm not getting answers from Salam. I've been trying to call them no answer aspecially the Klerksdorp branch.
