What am I supposed to do?

Hi, I've been wanting to redeem a reward but I can'tcause I need a phone number to do so...but the problemis, is that I don't have a number. I cant afford service and therefore don't have a phone number. What am I supposed to do cause I've spent months, almost a year getting enough points for just a 1.75 dollar redemption...just to find out I can't redeem it.

:)
