Keeps calling, I answer and they hang up and if I don't answer they don't leave a message. I get 6 calls a day.

Same here, this just started suddenly and I dont know what to do. They have called me roughly 6 times a day everyday, do you know who it is?

Same here but never past 8 P.M.

I just started getting calls from this number too...up to EIGHT times a day. Today they called at 4:30 in the morning and I finally fell back asleep at around 9:00 am. RUINED my plans for the day. How do we find out who's doing this? So frustrated!

Okay. I did some research and it turns out it's MCI World Com located at

520 East Liberty Street
Ann Arbor, MI 48104-2210
(734) 761-9426

They merged with Verizon which tells me it's a telemarketer or automated phone call, because I have AT&T. When I call the 7288 number, I get a rapid busy signal. So, I tried calling the number above and it rang and rang, then finally a automatic message came on saying "the cellular customer you are trying to reach is not currently accepting calls" If I find out more I'll post...
