unauthorised debit order riskfin/carebox ****

When you phone for assistance at FNB you are required to answer security questions to prove that you are the legitimate account holder and thereafter they still seem a bit sceptical. ********** on the other hand can simply deduct money from your account in the form of a debit order without any problem. FNB has allowed Riskfin/Carebox to debit my account with R99 without my knowledge.I have never taken out any policy with them or even heard of them. FNB lacked the security to prevent an unauthorised transaction. I called FNB to query this and after answering the compulsory security questions was told that it would cost R17 to reverse the debit order. ***, why should I have to pay for something that was not my fault to begin with? Instead of telling me that the debit order will be stopped for 12 months why don't you investigate this issue as it is obviously a ****.Currently you are not doing a good job as far as security goes as anyone can simply debit our accounts without our knowledge. A simple sms from FNB stating that the debit order was suspicious would have been adequate. FNB you can help me by ensuring that my money is safe from the likes of **********!
