Billing Disputes and Chargebacks

Effective Date: September 2026

We want to resolve billing and fulfillment concerns quickly and maintain a clear record for both the customer and the payment processor.

1. Contact Us First

Before initiating a chargeback, contact contact@psource-lab.com with the order number, account email, disputed amount, and a description of the concern. We aim to acknowledge billing inquiries promptly during published support hours.

Contacting us first does not waive or restrict any non-waivable right available under applicable law or card-network rules.

2. Investigation

We may review order qualification, payment authorization, communications, fulfillment records, tracking, delivery confirmation, and supporting photographs. We may request additional non-sensitive information reasonably necessary to investigate.

3. Resolution

When an error is verified, we will provide an appropriate correction, cancellation, replacement, refund, or written explanation consistent with the applicable policy. Approved refunds are returned to the original payment method.

4. Fraudulent Disputes

Customers may not knowingly submit false information or initiate a fraudulent chargeback. We may suspend accounts, cancel pending orders, refuse future transactions, and provide accurate transaction records to the processor or financial institution when responding to a dispute.
