Consumer to foot the bill for *********** staff

Bought goods, at the till price difference as to what is on the bar code, received a voucher, pointed price difference out. Goods credited back to my account but lost my voucher. Staff did not know what to do, store manager not bothered to help customers. Head office reception even worse and the person in charge of the easten cape not available. Hahahahahahahaha SERVICE IN OUR COUNTRY IS ONLY BUT A LAUGHING MATTER.
