This number keeps calling (I just wasn't answering - no messages left) multiple times over several days. I do live in Iowa, so I decided maybe I should check and see if it was someone I know. When I answered they asked for my first name, to which I replied "may I ask who's calling?". The girl hesitated, then said "Tonya". I told her this was a private number and please stop calling. (I should have reminded her we're on the do not call list)
The fact that she had to stop and think about what name to give tells me this can't be anything legit. And yes, if you call the number back it does say it isn't in service.
I missed 2 calls from this number within four hours. They did not leave a message and when I called right back, I got a recording saying it was not a valid number. My caller ID showed the number and Burlington, IA in the name slot.
I also got 2 missed calls from this number. Mine happened on two different days though. One was just an hour or so ago. I tried to call it back and it said the number was no longer in use. I knew it was from the east side of Iowa since it was a 319 area code, but I didn't know it was from Burlington.
