Who called from 2812021544

When the machine picked up caller hung up.

Called my business and when I answered the phone, they SLAMMED it down in my ear. OUCH !!!

Whenever I answer they hang up.  If I don't answer they don't leave a message.  If I call that number the call will not complete.  They call about 3 times a month

Called just came in, no ID except for "Texas". Didn't answer.

A woman talking to someone else in the background saying she thinks she dialed the wrong number. I just hung up.
