Having no last name is creating an issue

[jgyasu]

Hello, I recently applied for the GitHub education pack and I don't have a last name, it's completely legal in my country.

While entering my information on the billing page, they mandatorily asked for a last name so I put something random as my last name but my official identities and college admission details don't have my last name and as a result the verification failed.

What should I do? Please help
