Bad customer service

We went to Capitec bank at Nkomo village Atteridgeville where I was accompanying my sister, the withdrawal she was making was exceeding the daily withdrawal limit. She tried changing the limit on the phone to no success, the bank was still open so we decided to go in the bank. At the door was a guy by name of Marvin as per the name tag and a lady who did not have a name tag on. We explained the error we were getting when updating the withdrawal limit but they both laughed instead of assisting. They made it seem like we made up the error or treated us like we were somehow illiterate and didn't know what we were talking about. We were very disappointed regarding the customer service received, we wondered how many customers are laughed at when seeking for assistance at that particular bank. Only after we tried telling them their behaviour was out of line did they check the app and only to realise the banking app was not updated. How do you work with customers you laugh at when seeking your assistance and only assist when you done treating them like a bunch of illiterate people. Customer service is number one priority where the organisation is customer oriented. Marvin asked again after assisting about the error we were getting and he was not showing any remorse of how they treated us
