Robo-call with no voicemail message left, repeated calls from the same number. Tried to get me to verify information over the phone, which I refused to do. Said they couldn't then tell me what the call was about, started to got into a typical "escalated threatening" spiel and I said if you can't tell me what the call is about/what you want then don't call me anymore. Waiting to see how long it takes for the robo-dial to start again.
