Any of our products are tested and have demo site for every visitor to check.
We're doing our best to provide the quality products and high level of support. However, when it comes to 3rd party vendors conflict, features request or 3rd Providers Policy updates, we could not say anything in advance. For any change in product, we do also have public announcement.
You could also check out our Support and TOS at www.oxwall.younetco.com, there we do have Refund policy as well.
Client satisfaction is one of major point when doing business, but we could not do everything that clients request.
In case you'd like to purchase our product, kindly be noticed that our products are tested on default OxWall Core Script. So if your site has custom work or Core Modification, they might not work perfectly as in our demo site.
Regards,
YouNet
