AAA Product Options + Forms

I use to live this app however the past month every image the customer has uploaded I can’t view it says 404 error. I contacted customer service and it seems they have a language barrier, they are not understanding what I’m saying so the problem is not fixed as of now. They keep saying when we go to your site we see the option to upload picture. Yes you can upload but on the back end of the store the image isn’t coming through. I gave them access to order so they can view my problem, I haven’t received a reply. I’m not satisfied with the customer service.
