Trying to order seeds from Attitude w/ Pre-paid Gift Card, having trouble

I'm trying to order some seeds from attitude seed bank w/ a Vanilla Visa Pre-paid Gift card.

I'm running into issues when I get to the billing address screen.. what should I put for the BILLING address and name?

I never had to give info for the card when I bought it and I would like to remain anonymas.

What did you guys use and how did you purchase your seeds and get past the details? W/ pre-paid cards?

Thanks,
mE

Anyone that can help?

used my credit card.
