Disgusting behavior at FNB Portside

I app**** for passports using the DHA website, paid online and booked my biometrics at FNB Portside. I received the SMS to state they the passports are ready for collection. I went to the branch today to collect and was advised by FNB consultant that DHA systems were offline for under 30 minutes ( when I asked one of the people waiting in line, they said they are sitting and waiting for over 2 hours!). 10 minutes of me waiting, the FNB consultant comes to us and says that there's an "emergency" and they need to close the branch immediately, we will all need to reschedule for the next time. When I got outside I asked a other FNB consultant what had happened and she advised me that DHA consultants made them aware that one of their colleagues tested positive(this colleague was not at work this week). As we are having a conversation with this specific FNB consultant, I asked her if there is any alternative as to how I can collect the passports, she advised me to speak to the DHA consultant who walked out at this time. I approached him and asked for his advise and his DHA consultant continued to yell at me saying that it's none of my business, she said a colleague tested positive and that's why they can go home(speaking to me with no mask on) I asked her why she's not wearing her mask knowing that a colleague apparently tested positive. She shouted at me saying that it's free air she can do as she pleases and it's not my business if they want to complain to go home. This behavior is disgusting! The branch was full of people waiting for over 2 hours to be assisted, only to be sent home because DHA and FNB consultants are lazy! This is a waste of time and money for everybody! Their behavior is utterly inappropriate and I will definitely contact DHA as well! This delayed my whole process to apply for my visa.. Not FNB or DHA will compensate me for this! I will take this to social media as well to make people aware of the disgusting behavior!
