I don't know who the caller is? ...but always getting calls from here..when u try to answer the call, you just hear a click

Verizon customer Service.

They called my daughter and said I was $600 past due, which I'm not.  When I called back and individual answered, so I hung up.  I immediately called Verizon and they do not use this number, nor did they make business calls on a personal cell line.  It's a scam to get credit card information.

Caution, 623-208-5218 is a "spoofed" number, which means that whoever called you "tricked" your caller ID to display an incorrect phone number. Telemarketers do this so you cannot complain, but they failed... you can still file a complaint here to fight back against unethical telemarketers.
