Its a company wanting to sell credit card machines to business owners. We are not a business owner. Private residence. They call several times a day for a week or so - then are gone for a few weeks, then come back. I've talked to an actual human yet they persist in calling. So I report them. Not sure that helps, but it makes me feel better. ;-)
Called twice today. Caller ID the first time showed Better Merchant, second time as unknown caller. When I called the number back, recorded message said, "We're sorry, this number has not been registered."
