Do I even have to say it?
It’s. A. Scam.
Google themselves warn that “Google does not charge for inclusion in Google Maps. Be wary of invoices for services received — especially if nobody in the business remembers purchasing those services. Make sure to perform due diligence on any financial transaction.”
This is just the old 29 Palms scam, dressed in different clothing.
Google Maps is free to create, free to edit, and free to verify.
