I am having constant trouble disconnecting from calls with Jajah. It seems that this is a glitch that they know about and has been discussed in their forums. Phone calls do not disconnect for as much as 2 minutes after the call ends, and you get charged accordingly. Even if you disconnect before someone answers it keeps on ringing and you get charged for the call. Jajah are cooperative and refund money if you complain, but you cant keep contacting them after ecery call. That's asking too much. Shame, as otherwise it's a good service.
