Do yourself a favor, go after the source of the provider of this number. It's either a "network", communications network or "manager" They are the ones that sell, share or rent our info. It's the provider that we need to go after since FTC has failed to do that. Be an active consumer that goes after the source. The FTC is too "overwhelmed."
Called the number back and it identified itself as a Verizion National Call center trying to get my cell number and cc number to start a phone they said I purchased as WalMart. Or, load a prepaid calling card with my cc number. Called Verizon Fraud department and they are following up.
