Family Crafts review for ReviewXpo Product Reviews App

I downloaded this app to give it a try as I received a promo code when I purchased a Shopify theme. The code didn’t work and kept coming back with an error. I reached out to support and the first time it took them 5 days to respond asking what the promo code was I was using, I had already provided this in my support request. Two days now since I replied and still nothing, all I can say is first impressions are stay week clear of this company as they obviously don’t have any interest in customer service.
