Who called from 2135047055

I got a call from them saying I had inquired about a weight loss pill. I never did but I wanted to see what they wanted. It turns out they wanted my CC# to cover shipping. SCAM

SCAM ALERT

Received call wanting me to buy diet pills

Just had a call from this number.  Male said, "hello - hello!"  When I asked how I might help him he hung up.

I'd like to know how they can track our number, that's rather creepy and it's a stalking tendency. And why do they want to sell diet pills anyways, not everyone is obese or overweight. And diet pills can kill a person.
