Do not give them your credit card info. I got a new card and had "ONLY" used it for their service. A month later the number was being used all over the place and they were the only ones who used it.
The Federal Trade Commission has busted them last year and they are continually in the courts. Needless to say, the FTC has not contacted me about remotespy but they called about my own usage. Apparently my records are now in question. Cyberspy has gave them all of my records of tracking others.
Additionally, their software is not just 'remote' but it tracks the keystrokes of those who purchase it. If you think you are getting it to track someone else, be prepared to be tracked yourself. Finally, customer support is awful. They are rude and will call you a liar. Sophia Welsh, Erin Mitchell, Jennifer Shaw, and Tracer Spence work there and they all are scam artists.
