money making scheme Dischem Jabulani

jabulani mall --I bought a baby powder with a voucher which i thought was R50 only to find out its R100 , the teller told I cant get anything for R25 and that the R25 is forfeited. Kanjana if I am short of R25 are they gone give the product ? hell No . I boycotted clicks for its bad customer service .I want my R25 .and where is it written if I don't spend fully on a voucher I forfeit it .ene pls train the stuff to remember that while dischem is running a business pls note of this gentle reminder that u r also dealing real human beings. dont treat like **** when we come .
