I've had all the same experiences as all the other reviewers here. It worked for a few months back in 2017 and after realizing we could trust our kids cyberly, we chose to cancel the service. But we were still charged monthly. Couldn't contact support because their emails always get sent back. Decided to change the payment method to PayPal because my PayPal is empty and it'll get declined, but nope, it's been coming out of my bank instead. Tried to contact them again and the email was non-deliverable.
Less than an hour after I canceled my auto pay on my PayPal account I get an email from TeenSafe telling me to update my payment info. Really? For what? I haven't even been able to login to my account for almost four months now because there's no longer a login tab on their site. I emailed the support email that was at the bottom of the update payment message they sent me and wow, it's undeliverable, SURPRISE!
These people are scam artists and I think all parents being scammed by this company need to file a class action suit and get our money back.
Bottom Line: No, I would not recommend this to a friend
