Policy Cancelled without my Knowledge

Last month I went to enquire about my policy to find why Absa haven't deducted money through for the past 2 months, and I was told that my policy of 10 years full has been cancelled, I don't understand why because I went to my nearest Absa to inform them to change my debit order to the 10th which they've agreed. I'm very dissapointed because I've been a loyal member for 10 years and fail to understand why my policy has been cancelled. I want my money back that I have paid for the years because I have never requested that my policy be cancelled. What if one of the members pass away in the next month that means I won't be able to claim back while I've been paying for all years. I ask that my policy be reinstated and debit order be on the 10th. Policy number ***
