Who called from 4803600239

this is a scammer. robo voice says "welcome to the sweeps central sweepstakes entry line." the recorded voice then asks you to take their survey to win a prize. the questions they ask are like "have you or a loved one experienced pain in your shoulders? if yes press 1. if not press 2 to hear the next offer."

I answered the phone and it beeped like it was an answering machine. I said "hello?" and then it beeped again and hung up on me.

Some lady says:  "This is a recorded line, who am I speaking with?"  And all she was speaking to was my answering machine.  She proceeds to say "Hello?  Hello?  Can you hear me?  Hello?"

I blocked her number from calling me after that.

They called our office this morning around 7:00 a.m. (!!!) and nobody was on the other line when I picked up.
