Red Mountain Security & Fire Protection

"Red Mountain Security & Fire Protection" apparently mails out invoices seeking payment for "Annual State Required Fire Safety Equipment Inspection, Test and Certification" to large companies or companies that have multiple locations such as retail stores, etc. OR they show up at retail, warehouse, etc. locations and announce they are there to perform related services. Many employees at these field or non-corporate types of locations are naive and let unscrupulous service companies in to complete their hoax to legitimize an invoice. ALWAYS question, ALWAYS confirm.
We called this "company" several times over a one-week period and only get a suspicious voicemail greeting and no return call.
I believe the sham is that they hope accounts payable departments will assume it's legitimate and mail out a check without scrutiny. However, if businesses are responsible and review, require backup service receipts, have approved vendor lists, etc., like we do, it's unlikely they'll be successful.
