Poor service mtn vaal mall

I went to mtn vaal mall to do a Sim swap, the gentleman at the door asked if I'ts contract or prepaid I told him it's contract and he said I should join the que, shortly when I was on the que a white female senior citizen came asking each on the line how she can assist I also explained Sim swap and she said I shud remain on the que which was made up of people who came for payments, new contracts and renewals, the que was not that long at the front but it was stagnant, there were four tellers but only two were helping this two customers that has been there for over half an hour, the other two consultants looked like they were updating the sytsem or what not, as the que started growing people started to get frustrated and they complained when the old white lady came back to reassure us by asking what kind of transactions we where there for which was obviously just to calm our enxiety, well I told the lady I'm there for Sim swap which she again asked if Its contract or prepaid, which I also repeated it's contract, now at this point 45 minutes has gone past and those tellers are still enjoying time with the same customers that we found there, One lady and one gentleman came in on crushes as the que was growing, they were told on the spot that there is no Sim cards for prepaid they were advised to go buy a Sim card somewhere else and return with it for further assistance. Back to the que Eventually one left and now the que started moving like a gautrain, now when I got to the front I was told there is no Sim cards for contracts available, I totally lost it because I can't wait for an hour only to be told they don't have what I came there for, I asked for the manager who only said to me the guy must have thought they were delivered with the in comming stock and said she's sorry

No effort to say when I can come back or where else can I get help, it was like I'm at a my friend tuck shop where they just say no have it my friend
