Drekka review for AdRoll Marketing & Advertising

Update after AdRoll answer: Just proving this third party app recommended by Shopify is a scam. They claim I opted out to receive invoices which is something I never did and does not even make sense to have done. I have been working with Shopify and the app store since 5 years now and I have never had such issues and charges for an app we have never used: 80 USD per month! Unbelievable. Be careful! This app is a total scam. There is NO free plan and if you uninstall it from Shopify store, they still charge you so you need to specifically cancel via their portal. Also, they DO NOT send invoices if you do not "tick" on a specific place in their settings so if you miss the payments in your account statement (like I did), they will continue charging you without giving you any notice even though you do not use their service at all. And no refund! I could not even run and test their service due to currency issues on their side. @Shopify, do you even read the feedback about the apps you offer on your store? I can see a lot of similar cases and no action taken neither by you, neither by Adroll.
