The smarmy, dissembling customer service representatives responding to the criticisms on this website (and failing to handle the complaints of this company's customers) should be embarrassed and seek out worthwhile employment.
From stealing my money and applying it to some stranger's account then claiming to be unable to find the transaction, to canceling my paid-up account (on which I made a SECOND payment to stay current), to the obviously false marketing-department fantasies they parade on manipulable review sites, to their extortionate business model, this is nothing but a bunch of crooks feeding off struggling and broken families. No one working for this company has the capacity to feel appropriate shame or moral opprobrium, or they wouldn't be working there.
The idea behind this website is idiotic on its face. It saves your e-mails for you. You know what else saves your e-mails for you? YOUR E-MAIL SERVICE. All of the site's other features are of course also garbage in comparison to freely available versions.
If you and your ex can cooperate, just do so. If you can't, and you think an app will help, you're the crazy one.
