Has anyone noticed that with the ongoing jumia black Friday, if you happen to use a voucher your order will not go through and the voucher will remain invalid after failed payment? I wonder which kind scam be that! They won't allow pay on delivery once voucher is used and the jumiapay activated. Instead, the it will ask you to update your profile with a new password. No matter what you input it will keep showing error. Cancel the order and try using the voucher again, it becomes invalid. Jumia wayo!
