Garbage app that doesn't do anything the fact that they want you to pay for a service that they suck at implementing anyway is just a crime. There is no other company worse than AT&T when it comes to spam messages and calls. It's sad to say because I've been with AT&T for a ridiculously long time and I've never had a problem with their service but the morning noon and night spam and robocalls completely destroys that, it takes a five star service and turns it to one star.
