I called back and they say everyone is busy and to leave a message but when you dial its a silent time and them an answer machine saying to leave a message.
Called me one day a week ago several times. Didn't answer. Doesn't leave voice mail. Then called once each day for next 2 days. I know it's a pain in the [***] but u just have to ignore those calls when they call. I just temporarily silence my ringer by hitting one of the volume buttons.
