EcoLeo review for Stamped Reviews & Loyalty

I downloaded the app 2 weeks ago and it has been the most painful and excruciating experience to date with building our Shopify store. It was impossible to import reviews without their manual help. I am unable to customize anything. Choosing a specific layout for the reviews gives us product pages with different review layouts (some are in columns, some masonary) making our product page look messy and unprofessional. Cannot change font colors, style etc. It's been over a week I have been asking for help and following up and my concerns have still not been addressed. I get vague responses that they will look into it and then crickets. Looking for another app now.
