Bad service I went to Ackermans in modimolle the one in town in Thabo mbeki street I waited for 1hour in the que just to pay 3items only when I arrive there was only one cashier working n been told that they a offline they only want cash, by their rude cashier.i find this very rude cus she could told us early or put a notice so that we don't wait that long for nothing.n its month end u can't hav one cashier working on dis busy day
