Their one-day deal for boost is very misleading. While you might think you're paying 3$ for a day, it's actually a daily renewing subscription. It's also very hard to see that you are subscribed daily because the UX hides it very well. Customer service refuses to collaborate in finding an agreement, and categorically refuses to issue any refund. It resulted in an abusive 260$ charge over a period of time because it was never clear that I was subscribed.
