Policy Cancelled

I have been a member of Liberty Life since 2013, I have 5 policies with them. I took 2 new policies this year which are supposed to help in a time of need, all these policies premiums have been deducted from my salary directly for all these years. This year however was different, I signed off on these 2 new policies and received my contracts but on the 13 November 2015 i got 2 letters from Liberty stating the policies have been cancelled and no longer exist due to premiums not being received. I contacted Liberty and spoke to Londiwe who was not very helpful, she told me I made a stop order but the money was not there for them to deduct. What stop order, i surely am not a volunteer, I work and get paid every month and i am very well aware the money must be deducted from my salary by Liberty. I work in the customer care field myself and should a client enquire about something i have no answer to, the best thing to do is to enquire with your superior not to answer me like you just wanna get me off the phone. I am highly dissapointed with Liberty, I don't take out policies for fun or because i have extra which i have nothing to do with, i need these polocies. I am highly dissatisfied.
