Why did Liberty Life stop debiting for my policies

I have not seen a company that is so frustrating and useless like liberty life. I have been a loyal customer but the recent service that I am receiving from them is nonsense. I have 3 policies with Liberty Life. The policies are for R130, R225 and R525 which is been deducted from my bank account on the 15th of every month. To my surprise I just downloaded my bank statement and it indicates that Liberty Life has not been deducting for the past 4 months. My question now is who is that person that stopped my debit, and who gave them authority to do that. now I have to pay close to R1500 so that my policies can be up to date. Where the hell do I get R1500 from? Is this Liberty Life way of ******** customers by stopping the deductions so that when I want to claim I will be told that my policies where not paid. To make matters worse I have not received any call, email or SMS from Liberty Life indicating that my policies are behind. Maybe I have over stayed my welcome at Liberty, and its time for me to get a competent insurance company that wont give me stress.
