They are a junk fax list builder, nothing more. That's why the faxes they send aren't connected to any real companies with any real contact info. We get several, including one for "seal coating" with a Missouri phone line to get an "estimate" that doesn't go anywhere.
They know they're operating in violation of the Federal DNC registry and the Telephone Consumer Protection Act, but they don't care. They're just banking (literally) on people calling the 800# at the bottom to get "removed" from the list, because that's how they build lists of live fax numbers to sell to other junk fax senders.
These people operate as fly-by-night operations, hiding their identity, and are likely operating from overseas. Block what you can, because there's no way to report these [***].
Received another junk fax from this number. The current fax advertised Lakeside Roofing. I will post separate entries for the listed callback and unsubscribe numbers.
