Lost Driving License at the Bank

On the 22 December 2017 I went to Standard Bank Northgate branch to collect my credit card at 14:30. Went to the Teller I was assistant by Sharon Masina the branch manager. I provided her with my drivers license to assist me while she was busy on the PC she said the PC was slow so she used the next PC of which belongs to the other consultant while I was waiting for her to help me. The next thing she lost my drivers license could not find it. She checked and still could not find it. She managed give me the card that I came to collect. Now problem is that my drivers license is still lost noway to be found. She decided to check on the footage camera and still could not find anything. She explained about the footage and I left my contact numbers with her and she promised to call me back at around 17:00. She called me back to explain that she could not find my drivers license with different explanations that didn't complete getting my license back. My worry is *****, using my drivers license and other resources and other ilegal activities since it was lost in the bank in the hands of the Branch Manager. This is bad service that I have received from standard bank and I find it very careless. As a customer we are supposed to feel protected and safe with our banks with our private documents. This situation left me hopeless and stessfull more especially that its festive seasons. Please assist me in this matter to be resolved. Unhappy Customer
