There's no specific way to deal with a charge back from a customer. PayPal allows a customer to complete a chargeback within 45-days! This is why our Refund Policy in our Terms of Service offers a 45-day money back guarantee. If a end-user completes a Unauthorized Transaction Form against PayPal and our business, we work with a Legal Advisor in order to obtain whether the claim is really unauthorized. We normally tend to refund all customers for all services besides Dedicated Servers as our prices are 50% below market value.
