Official customer information
Customer terms, cancellation and refunds
Understand delivery arrangements, cancellations, refunds and customer rights before placing an order.
Order scope and availability
Each listing defines the offered book or professional service. Booking and delivery arrangements are confirmed separately where required. Fees do not guarantee a particular educational or professional outcome.
Printed book delivery
The buyer provides accurate delivery information. Postal shipping is free to book customers and paid by the seller. Estimated delivery is 10–14 working days after order confirmation and stock verification; the destination and carrier may affect actual timing. Report damage or incorrect items with the order reference; requests are reviewed in line with applicable consumer protection rules.
Services and cancellation
Appointments, deliverables, rescheduling and cancellation conditions depend on the agreed service scope and the stage of delivery. Any refund request is reviewed against the transaction, applicable law and agreed terms. No unconditional refund or fixed fulfillment deadline is implied by this page.
How to raise an order concern
For an incorrect item, delivery concern or disagreement about a service deliverable, contact the official support email with the order reference, a short description of the issue and any relevant non-sensitive evidence. Do not send card security codes, passwords or complete payment-card details. The order record and applicable consumer rights should be reviewed before a decision is communicated; the wording on this page does not remove statutory rights.
Privacy and communication
Registration and formal communication use email. Phone authentication is not used. Postal data is requested only when necessary to ship physical products. Eitaa student support is restricted to eligible verified purchasers.
