I keep getting calls from this number too! Whoever calls never leaves a message so I am lead to believe that it is a telemarketing call. I refuse to answer because I don't know the number and plus the call is coming in on my cell phone. I recently signed up for the DNC , and that was only recently and I know that it will take some time for it to become into effect.
After recieving 10 calls A DAY from this number, I attempted to call back. It rang twice, then fell silent. Upon turning up the volume on my cell, I could hear a clicking noise, as though someone were typing on a keyboard. I hung up quickly and without a word. Don't answer this number, and do not try to call them. Its probably best just to get this number blocked.
They called me 3 times in tthe last 2 days. I never answered and they never left a message, but they don't seem to call long enough for voice mail to come up. Don't know who it is.
