Invalid code on sign-up page

I referred to one of my friend(in India), and he has been trying to sign-up on Payoneer for the last 2 days, and he is really frustrated and tried this more than 50 times.
Below is the message which he gets where even after entering the correct OTP received on mobile number, it errors out saying Invalid code.
Customer care doesn't work for not registered users and on chat, I got this toll free number for India 80044-04022 which is not working, so we don't have any idea how to open a new account.
Just went through a couple of messages and seems a lot of other users are also facing the same issue.
PS: he tried callme option and tried Chrome, safari and firefox browser but no luck.
