<human>:  What should I do if a customer wants to dispute a purchase?
<bot>: If a customer wants to dispute a purchase, the first step should be to contact the seller directly. You should have all the relevant information needed to address the customer’s dispute, such as purchase details and proof of purchase. If the customer is not satisfied with the outcome of the discussion with the seller, they may choose to pursue a dispute resolution process with a third-party organization such as a credit card company or a mediator for conflict resolution.
