Invalid voucher codes

Made a purchase on Hyperli. Downloaded my vouchers to redeem....only to find out that ALL the voucher codes supp**** to me are INVALID. Tristan @ Hyperli just revers me to TIXSA. According to Tixsa the codes will only be invalid if Hyperli supp**** the incorrect/invalid codes.

So now R1300 later. I'm sitting with vouchers that I can't redeem and not one of the companies are attempting to fix your mess!
