Ugritone review for OptinMonster Email Popups

Otherwise it's a good app but one notorius thing happened: I added the app from shopify app store, and it does say 49$/month pricing. I approved and even got an e-mail from shopify about optinmonster saying: You‘ve approved a recurring charge for an app with a 30 day free trial. and it also states Charge amount $49.00 every 30 days. STILL after 30 days without ANY warning or notification the 30 days trial ended and optinmonster stopped working. The account on optinmonster said that I don't have a plan selected and I should choose one. I had to choose the one we had and update payment info directly from optinmonster site. But there's not 49$/month option. There's only an annual plans where you have to pay the whole year beforehand, and you cannot get a refund even if you choose to quit during that year. Of course I did not pay around $500 at once so I chose a cheaper plan. This feels like a scam, and ended up Optinmonster losing revenue, and of course we too since it took a while to get this figured out and we had to stop advertising etc. until it was solved.
