They have called me up to 5 times a day and do not leave a message. When I called them back, there was no answer and no recorded greeting. Most likely an at-home-telemarketer or scam artist.
Obviously a call center. Lots of chatter in the background. Called my business although they did ask for a person by first name only. Strangely it was my daughters name. They then hung up when they realized it was a business. May be using caller ID masking technology. Came up as Medtronic a medical electronics company not far away but in a different area code.
