First, thank you for taking the time to share your experience with everyone. I think that you’re giving a realistic assessment of the situation, which is valuable to everyone. In my opinion, the vendor should work with you to resolve the situation, including a refund if the service can’t meet your requirements as you had an honest misunderstanding of what the product could do. However, that’s my personal opinion about what’s fair.
The 3DVista service could be considered a big investment for many boutique photography studios, so I am sympathetic to the financial hit if you can’t use it to show your photos in the way that you want to. The last 18 months has been tough for many people and it is my hope that the vendor works with you to resolve the situation.
