As Kayla's eBooks are digital, they cannot be physically returned and/or exchanged and are considered a final sale at the time of checkout. There is also no way for us to determine whether or not they have been accessed.
Our 'no refund and exchange policy' is stated in the Terms and Conditions which are agreed to at the time of purchase. However, if you wish to discuss your purchase further, our Support Team will be happy to help. You can reach out to us, here.
