Zaypay BUG !

Hello,
My cousin got his internet at home and we wanted to buy him windbot license fast the payment was 4,99€ for 19.5days.
We sended the message from phone and answeared with yes to continue the payment.
After that we got message that the payment has been drawn from phone but the problem is that we couldnt press continue on the website...
I got also some screenshoots from that :
