I keep receiving Robo phone calls and letters trying to sell me an auto warranty. When I block their number with my Ooma device, they simply call from a different number, location, and /or name. When they call, they don’t give a name. On letters, they don’t give a name, type of company, (LLC, Corp), or address. I called their 800 number and asked for their company name, location, and their Federal Tax ID. He responded only with a name, "Vehicle Solutions." I’ve asked these people not to call, but they persist. When searched, nothing comes up. I believe this is a scam.
