What happens if a purchase is returned - will I receive a chargeback?

•  As a rule: the refunded amount is deducted from the total transaction value that we counted toward task completion.
• If the task has already been successfully completed and a return occurs afterward, we no longer take it into account (customer-friendly approach). However, this creates a risk that a user may make a purchase at the end of the month, have the task marked as completed, and then return the item later.
