Rebuy Personalization Engine

Uninstalled because I experienced the most unhelpful customer service of any app I’ve worked with. I was excited by the features and screenshots offered on Rebuy’s Shopify page. I didn’t want to achieve anything complicated but I just needed some help to position the app in the right position on the product page (it's automatic detection didn't work) and to ensure it appears in the same way as an example screenshot shown on their site. Perhaps I was wrong to hope one of your team members might be kind enough to help me - by requesting permission to my store - but instead I was given short replies and sent a link to a help guide (which I cannot understand, unfortunately). A great pity as I had hoped this would be a great solution.
