Misuse of personal information

I went to one of their Branches(Grahamstown) to withdraw from my Savings which i have with them. i was asked to bring along my bank statement and id. which i did.

I asked what is the bank statement for, the consultant told me that, it is to confirm that the money will be going to the rightful owner, fair enough. I was advised payment will take about 5 working days to reflect into my bank account.

A day later, i received a notification that a credit check enquiry was done on me by Old Mutual. I went back to their branch again to find out why did they do a credit check on me without my consent and what is it for ? i only went to them to withdraw my money. I actually got the same consultant , who confidently said, she wanted to see if I "QUALIFY " for a loan. UNBELIEVABLE!!! i asked her without my consent?? she clearly has no idea of the impact of what she has done, i requested for a Manager, there was none !! was told she will be back the next day as she was on leave, Second in charge also on leave. My score has been affected by their *********** staff member which makes me even wonder if they are Accredited ???
