No cancellation of refund policy.
If someone paid for an ebook, we can’t refund him as it is a digital file. After payment, you can download the PDF file, and it can be multiplied in any method. So this is not possible to refund.
We can provide the file if you cannot download the file after payment.
Also, we provide you the ebook if you lost that pdf book by any means. We provide the book download link up to 6 months after the payment if you provide the detail which you added when purchasing the ebook. You must give the correct email id & name to get the copy again.
