Have you sent your friend a referral, but you didn't receive your 5€? Please make sure that:
The invite wasn't forwarded: Each invitation link is unique and can't be forwarded.
Your friend registered with the phone number you sent the invitation to: If you sent it to the wrong number simply wait 7 days (after sending) for the referral to expire and send again!
Your friend has topped up with at least €10: this has to be done within 7 days after the referral was sent, we recommend topping up when you first open your account!
If none of these help, please contact support via intercom chat, or send an email to email@example.com
