Support does not respond and will not give refund…

Support is non existent… The plugin is okay, however support is non existent. The videos demonstrating the plugins capabilities on the website are of every single addon, you can not replicate this functionality with individual addons it is a little deceiving. The plugin also cannot be used to SMS existing customers without manually entering their phone numbers again. After learning of its shortfalls for my situation and requesting a refund, there was no response from support. I only managed to get a response when posting on the public forum. They would send a short email, I would reply and then again I would get no response. Now 3 weeks later and still no refund and only superficial responses from support. By far the worst experience with a Plugin author…
