I heard a lot about the website www.privacystar.com and decided to try their app. It was for free within 30 days. And it was easy to follow and see, who has contacted you and if there was any harasment, and if it was necessary you can block the person and stop any further calls. The app worked great, but my agreement was short with them and they didn’t inform me and stopped the subscription. I still don’t get it, why they haven’t warned me about it. I searched contact info, but it hasn’t been posted on the website.
