they called my office line at 6pm, no message left

Called my cell - once a day: if you answer, it just hangs; if you missed the call, they don't leave a message.

They called my cell even though I'm on do not call list. This better not become a daily event.

Called my cell, picked up, then just a hang up.

When I picked up the phone there was a short pause and then a lady started talking. At first I thought it was a real person but quickly found that it was an automated response. If you don't answer the question the lady instantly says "Hello, Are you there?" and will repeat herself. If you say something in the middle of her question she continues the question. Stupid scam trying to offer a free cruise.
