horrible service

I was at Durban ackermans the one in west street which is near Woolworths. I can not even begin to explain the level of bad service I have recieved from Msizi Gamede his name tag was written Pencil.. I was there to do my exchange after i had done a laybye he was so impatient and i kept asking him to be patient he kept on passing remarks and we ended up cancelling the exchange and i left and told him i will come back another day he went on and told his line supervisor that he is tired of my exchange because i had messed it up.. but if he had listened to me and stoped being impatient he would have been able to get my exchange right I am so disapointed i ended up not doing my exchange even his supervisor was next to him but she did nothing awful service!!
