If a person who purchased from a link you sent returns a Product before the Brand's return period is up, KwikCash commissions will be removed from your account, as well as any cashback that was distributed to the purchaser.
However, if said person who returned the product sends links resulting in waves of influence, you will still get paid for purchases made from that person's links and waves.
If you have any issues with a wave or link of someone who has returned, please contact Support@kwik.com
