Just got a call, asked for head of the house, then she said she'd call back. Not sure how they got my cell number.

Ignore them!

Received a call from someone with major attitude issues. Asked for a family member who doesn't live with me. When I asked who this was, her reply was "no message. IS THIS ****?!" Sheila or whatever your name is from whatever cancer research company etc, if you're trying to solicite money from people learn to speak to a person, regardless of whether it was the intended person or not.

No message left, and after I've read these reports I disregard the call.

Asked if head of household was available, replied no, they said no message and hung up. Most likely scam or sales call.
