Disgusting service from security company at Absa

Good Day I went to Absa connect in 9 lothbury road to drop off some documents and security said they were not letting anyone in I then asked why they are being so full of **** and the security gave me a lecture about how disrespectful I was being the comment was not directed at him i even apologized and explained and he carried on shouting profanities at me, His supervisor Elija then jumped in he was very helpful but was also getting shouted at by this guard that did not want to give his name, You might want to use a security company that treats your customers with respect
