How strange that we all have the same story. I called AT&T this morning and they told me that I can change my number, pay to block it or ignore it. This has been happening to me for about 1 month. Oh well now I just ignore it since I can see the number that is calling. It's always the same number. 404-709-5115 Some one must be really bored to take the time to bother so many people.
Wow this is pretty weird, and dido for everything everbody else said. I never picked up and when I call back, it says this call cannot be completed or something like that. Who or what company is doing this and what do they want? I really don't know if it is a prank call or what, it doesn't say unknown caller, but I don't know who it is so it might as well be unknown. I'm want to look more into this.
