First, make sure that your friends buy a Y2Mate plan within 7 days after they registered via your own referral link. If their purchase happens after those 7 days, you and your friends cannot get the rewards or discount. Second, if your friends buy a monthly or annual plan, you need to wait for 7 days to get your 7-day or 30-day free VIP license in order to make sure that they don't make a refund. In the same way, you need to wait for 14 days to get your 365-day free VIP license if the friends you've invited purchase a lifetime plan.
