poor service

i went to telkom store in kimberley at the pavillion mall on the 02/05/2015 ,i asked a gentleman by the name thanzi sentze at the counter if they do sim swaps and he said yes and i must standin the queue which i did and to my surprise when it was my turn to be serviced he tells me i must stand aside so that he can assist customers who are there to make payments,and i asked why them he says i must wait for the payments customers to be helped,because his dealing with payments first,this was a very bad poor service and an inconvenience for me after standing in the queue for 45 minutes and to be told i must still wait further for people who came after me to be assisted.
