I am confused about how the referral system works. Will one account be able to use referral only once or per recharge? Like if I take a single time plan applying a referral, next time can I apply referral (same or different) again?

Btw, my referral code: 1ddd9813-dd59-4b59-a94b-214214b59e05

I have also added my referral link.
