I Love Tunics review for Amazon by Codisto

I signed up a month or so ago. Followed their instructions to setup amazon id's etc - verified over the top ID requirements on the basis of info provided that first 50 orders will be free. I thought that's great way to test waters, however within a week of joining I get charged $64 - keep in mind my listings were not even active. I contacted the app team and was told they are NOT amazon ....and 3rd part = why has Shopify & app developer not made this clear to begin with, also app developer apparently has zero leverage with Amazon - so I got handballed to Amazon who have till date not refunded my money. Just upset at the whole BS
