Pathetic service at madprice uitenhage

I had bad costumer service at madprice uitenhage shop on the 27/11/2018 at 5pm the tell was shouting next several times whike we were still doing our last shopping until one African lady approaches us and told us the tellers switch computers at 5pm irispective of there's costumers inside. We decided to go and leave the item that we already took when we were at the door we asked the security for the store manager or owners contact no and security asked at the lady at the till then the response was she doesnt know the numbers' and he must close the door . This was our first pathetic costumer service we have ever encountered in a retail store.
