Don't you find it strange that no one answers, or the phone is always a busy tone. Multiple people, from multiple locations and places get the same call, same results. I wonder if it's a survey of some kind. The Marketing company calls to confirm numbers that are active and sells that data out.
4 calls in two days. Nothing is ever said. If this is some telemarketer they are not doing their job all they do is call and hang up. Harrassment is illegal and if the calls don't stop I will be calling my phone company to take action against this number.
