Voucher

Good morning I went to shoprite checkers at Sanlam Centre Samora M****l Dr at Nelspruit to reedem a shoprite voucher to a gift card the cashier began to make a call to her friend while assisting me with the voucher then after that she made a video call to her friend while working that's how she put R250 instead of R2500 to the gift card then the time I sign the slip that's how I saw it's R250 not R2500 I told the cashier that she said how are we going to fix this I ask her how can you ask me that because you're the one who did that I asked for a manager she insisted to cut the story short I want my voucher back because I don't have have food here and no feedback from shoprite
