********** by Supermarket

Hi guys.. I we talked to a supermarket in Westpark Kwaggasrand to draw money. My house had bn broken into needed cash to pay person fixing the damage. I received 2 reciet from atm but couldn't figure out where the was dispensed. The balance showed me us about being no cash. I left and thought ask go back n ask. Second slip was actually a voucher and money given out at the till before with a catch. To get money I had to buy something from R5 up. What kind of service is this.
