soundofpearlslondon review for Fomo: Social Proof Sales Popup

We chose a free plan as we think the quota is enough. Then we found out we have been charged 189USD, 149USD,89USD for a couple of times. We then checked further and found this "Smart" FOMO serectly "upgraded" our plan (more expensive one). They set an option (in a very hidden place) saying: Auto Upgrade Plan enable. Obviously we didnt know we have to "disable" it, and thats why they leave it" enable" and automatically upgraded our plan. I doubt is is a scam, because we don't have that great traffic for the past few months, and they said it showed x amount of notification so charge us more (they said we have 30k notification which we don't believe it) Now this FOMO app chardge us around 1000USD and we barely have any sales. AVOID FOMO!
