EXPLANATION PLEASE !!

Explains:
1. For mena region is a service called onecard and is actually sponsor the MENA players for online games ( the difference in price is payed by onecard as z8 still receive the full price for any amount of zp )
2. Onecard is only for MENA region ( see onecard policy and country available to use-it ) and they require a lots of personal details including ID card in order to provide you are eligible to use onecard service
3. However if onecard users decide to use those codes in other purpose ( as buy onecard codes then sell them to other users ) is against onecard policy and they will ban the onecard user + ask money back from z8 , when that happen the z8 user will be banned for chargeback.

My advise is to use only available payments you find for you on z8 website.
Using anything else may be a scam (as you pay something to someone and never see anything ) OR you will end being banned from game sooner or later.

P.S. And forum is not the place to made accusations ( as post image about other users / players , just see forum rules https://forum.z8games.com/categories/rules-conduct ) ,
When you have such evidences please send a support ticket, or if is something on discord : report the user to discord for scam (or any other reasons may apply) and if reported discord user is part of CF discord you can also dm a mod or GM on discord about.
