Textbook way not to develop a business relationship. Robo calling with nobody on the line and annoying your prospective customers. Bravo brainiacs. Blocking this number, suggest you do the same.
CallerID read voip and a long string of numbers, maybe even the phone number but I'm not positive.
I answered the phone with the company name and instead of hearing a recording or person respond I heard what sounded like someone turning on or off a speakerphone. I said "hello" and was hung up on. How is this a profitable business model?
