Poor service received while enquirying about the lost driver's bank at Standard Bank at Wits

Hi I would like to complain about the bad service received from Standard bank, the Wits University Campus Branch. I went to fetch statement on the 5th of November 2019. I used my drivers License as the identification, however I believe I might have left it there as it was the last time I remember using it. I then went on the 25th of November 2019 to check if it is there. To my dismay, the lady who was on duty (which is not the same woman who helped me on the 5th of November) dismiss me and said there's no driver's license that was left there. she did not even bother to check it. I then left and came back the following day which was the 26th, thinking I would find a different person on duty. I found the same lady who pointed us to a mini locker and without opening it and checking its contents in our presence, she just said, there's nothing in there. I do not understand how on earth does the standard bank train their employees to treat customers like that. I am sure that I left my License at that branch, but now they are not even willing to help me. Unfortunately I do not recall the name of the lady who helped me on the 5th.

Please help to get my driver's license back from standard bank branch at Wits.

Regards MDR
