Hello Barbara,
We are sorry but we didn't get any message from you.
it would be great if you can send me your message thread ID or Invoice ID to check the occurred problem.
Also, you can send me a message to direct about your problem, then we will fix it immediately.
Here is proof of your message thread that you contacted with PrestaShop addons team NOT with us :
Proper to PrestaShop addons policy we have to check the problem before the Refund process. If our technician team cannot solve the problem then we can begin the refund.
Contact to MigrationPro: https://addons.prestashop.com/en/contact-us?id_product=8934
Thank you for understanding
Have a great day
