I must receive my referral code discount but again you did not pay it to me

Behnaz, it's a shame that it's not easy for you! You have the proof that it's supposed to be honoured so keep reaching out to them, you're on the right track!

You have to follow up with the service again. We are users like you here in the community.
Do you see it in Profile => Referral bonuses? If yes, what is the status?

As mentionned above, it's probably best to contact them again throught the chat. Fizz should care about your situtation.

Hi Behnaz,
If you qualify for the referral credit, you will see it on your account:
My Profile-> Referral bonuses
The credit is unlocked after the new customer makes their second payment. Once it is unlocked, the credit amount will be applied to your next bill of that plan.
