I don't know who this is but they shouldn't be calling.  I signed up on the Federal Government's do not call list.

Criminals and telepests have no regards for any lists, stealing from, cheating, and pestering the public is their motive. Check out that prefix, too. 555 is used for television and directory assistance so you can probably bet it's a spoofed number.

i dont know

A person calling from 786-555-1818 has called me 3 times so in two days, Sat & Sun, leaving a message from first two calls stating this message is for me, Greg Lawrence, and identify themselves as Com Care Pharmacy, which is my pharmacy, in respect to a delivery.  I never have any medicines delivered and this pharmacy is closed on weekends.

I just got a call from this phone # today. After getting calls from unknown numbers from Indiana, Alabama, Connecticut, & New Jersey to mention a few... I learned not to answer as my iPhone data including using my iPhone # will I was mysteriously locked out of my iPhone. My bill was way over in data charges and my credit cards were used to purchase items I never bought from online stores.
