INCORRECT BILLING

In 2009 an amount was deducted from my pay for a policy with clientelle. After months of phone calls and frustration they managed to find out that I never took out a policy with them and I was paying for someone else's policy. They finally reimbursed the amount deducted but all cost incurred to sort the matter out was my loss. Now it is happening yet again. Two premiums have already gone off my pay and the one for May is already reflecting on our persol system. After the first deduction I immediately contacted Clientelle and they promised me feedback within 5 working days. A month later I had to contact them again and after threats from my side as well as a demand to get satisfactory answers within 5 working days I finally received a reply on the 5th day to say that my complaint has been forwarded and the matter will be followed up. How long do I still need to wait for it to be resolved and how do they intend to compensate me this time around? They told me they think the wrong persol system was accessed when the debiting details were entered. This is their negligence not mine.
