Regent Insurance *****: 14 months of theft!!!

I received a rejection letter after my car accident (21 November 2014) informing me my secondary insurance, Regent, will not pay, and my insurance would be cancelled and all my money would be returned to me. Fine I paid my car myself. Now I've just noticed that they have been debiting from my account. I've contacted them on numerous occasions and still no word regarding my refund. Surely this is *****, as their debit order comes through my Wesbank statement? I've contacted Wesbank as well and they say there's nothing they can do. Now I have no other outlet. I just want my money returned to me.
