I got the same call, I filed a complaint with the FTC you should as well verizon has also confirmed they are calling from a cell number- Take action and fight back. Make a comolaint with verizon to have the number shut down and report it to the FTC
Scam! It's b.s. reported the number and faxed them a cease letter. Do the same to protect your rights. Also register with the National Do Not Call list.
