this number has called me about 15 times in the past 4 days and only once did someone talk to me.  They were trying to sell Dish Network, but I think it was a scam.  Every other time they've called and I answered they'd hang up on me or if i missed the call they'd never leave a message.  They start calling me around 8:30 in the morning and this goes on usually until 3 in the afternoon.  When I try calling it back it says the subscriber is not available, which sounds like a message on a sprint phone.

this number calls my phone atleast 5 times a day, no one is there when I answer, and it is a constant busy signal when I call back at all times of the day.

This number (866-255-6988) has called 2 times, as of today, and numerous other times, starting about two weeks ago. When I answer, the caller is silent and then the call is disconnected.

this has happened to me as well

calls my cell and no one there

That # has called me 5 times today, but it only rings once! Not even a chance to answer it. I try calling it back but it says the number doesn't exist!?!
