I cant redeem paypal money

I spent a month trying to get to 2500sb and i just got it today but while i was trying to redeem the paypal reward it wouldn't work even though i double checked my information. I clicked the link for help and it said i needed to verify my PayPal account by linking a bank account to it but the problem is that i don't have a bank account so i honestly don't even know what to do at this point and id appreciate any help. thanks
