Returns & refunds

Last updated: August 20, 2026

Who sells

XMA Capital S.A., a Brazilian company registered under CNPJ (Brazilian corporate tax ID) no. 24.261.825/0001-28, e-mail contato@mariodealencar.com.br, phone (48) 99106-7972.

Right of withdrawal: 7 days

As the purchase is made outside a physical store, you may cancel it within 7 calendar days from receipt of the product, without giving a reason. This is the right guaranteed by article 49 of the Brazilian Consumer Protection Code (CDC).

To exercise this right, write to the contact e-mail with your order number and your intention to return. You receive the shipping instructions and do not pay the return shipping.

The print book must come back in resale condition, with no markings, folds, tears, or signs of use. Once the product is returned, the amount paid — including shipping, when charged — is refunded in full through the same payment method used in the purchase.

E-book

The e-book is also subject to the 7-day window. As delivery is immediate and the file cannot be returned, a refund request implies cancellation of the access link. Requests made more than 7 days after the file was sent are not refundable.

Defective product

If the book arrives with a manufacturing defect — missing, swapped, or illegible pages, detached cover — or damaged in transit, report it within 30 days of receipt, with photos of the problem. Once the case is confirmed, you choose between a replacement copy or a full refund, with no shipping cost in either case.

Refund timeline

• PIX: within 10 business days of receiving the return or confirming the defect, to the same key used for payment.
• Credit card: the chargeback is requested within the same period and appears on your statement according to the card issuer's calendar, which may take up to two billing cycles.

How to request

All exchange, return, or refund requests are made through the contact e-mail shown in the footer, with the order number in the subject. The response comes within 2 business days.
