Worthless support

DO NOT buy this plugin. I have been literally trying for over a YEAR to get support upgrading their product to the latest version because of a technical error reported by their software. All I get are empty promises to help, then nothing. Told my license was expired even though I never got help when it was active. Fine. I renewed the license hoping for support. Nothing. Then promised a free license for the trouble. Never received despite repeated attempts. Can’t get a refund now because too much time has passed and I have no faith at this point that I would ever see it anyway. Communication is practically non-existent for a paid product. I’m tired of wasting my time and money with this guy. Obviously he doesn’t know the answer to the problem or doesn’t care so instead it’s ignored. Buyer BEWARE!!
