Called business phone, answered with my first name. Caller knew my last name already, then just hung up.

Number called my business phone, which I answered with my first name.  Caller knew my last name already, I said this was the person they were asking for; They coughed in my ear a few times & then just hung up.

Person with unintelligible accent asking for two different people at our business location. It sounded like they were claiming they were from a doctor's office, but I couldn't be sure. Hung up when I said they were not available to talk.

The person called my office phone (Asian accent) and when I answered, I identified myself by my first name only, the person asked if I was Jacqueline M_____, to which I answered, "yes.' They giggled and hung up. This is too freaking weird!!
