Lottostar ****

I bought 1voucher on my app on over a week ago , I reported it on their chat to Agent. Was told the matter will take 48hours, mind you the voucher was bought on my bank app ND even today nothing has been done dey always saying how they escalated the matter. ND another thing dey set their system for 20%win 80% loose system. It's not 50/50win lottostar it's 20/80%...Day light *******....now even worse with vouchers as well it's not guaranteed u will use ur voucher once bought
