Product Add-Ons for WooCommerce

This plugin is a mess since the last update.
Fields are mashed together in cart instead of appearing on individual lines. This has to be fixed! It looks completely unprofessional.
Also, there is no way to limit the size of uploads, without changing things on your back end PHP (thus limiting the administrators as well as users).
For a plugin that I PAID for, I expect to get some kind of customer service, and I’m getting no response.
