Called my cell and didn't leave a message when I didn't pick up. A search shows this number associated with a bunch of small businesses all called Jim's. Jim's Lawn Service, Jim's Electric Company, Jim's Appliance Repair, but these businesses are located all across the country in different states. Very odd.
Same for me. I was driving and didn't pick up and they did not leave a message. Some other message boards have reported the usual credit card scammers, but I cannot confirm that. Not someone I know though, so I am blocking it.
