Gifty ‑ Gift Wrap & Options

I use this app and have problems no one bothers to get back to me with support. I have contacted them 6 times and to no avail

I started the free trial, the app didn't work at all, reached out to support, they told me to wait a few hours, as they were running updates, I have now waited past my trial period, I am now being charged for the app, and it's still not working. I have reached out to support 3 times, and had 0 response. I am still waiting, as it's functionality that I want to use...
