THey called my business cell phone and they did not respond. I suspect this is a robo call looking for available people to call. I made some call list and have been getting these calls from difference numbers for a few weeks.
I was just called by this number and it was a telemarketer for business ventures. The minute I answered the phone, I stated that I was on the "Do Not Call List" and the female person on the other end, replied, "Well you are gettin this call today." Then hung-up right away. I get several calls from each week from numbers like this and they don't even check the DNC List. If I had the business name and address, I would file a small claims charge for each time they call. You can check your states laws to file.
