FloraNu review for Gleam Competitions

This app is a complete SCAM!!!! I signed up for the pro version which is a subscription charge of $49/mo. Then I get a bill for almost $200 USD for a month and it says on the bill "Up to $5000/mo of usage charges". I have NO idea how to set the maximum spend limit. I DO NOT want to be spending this much on this app. AVOID AT ALL COSTS.
