Who called from 3603409505

I have registered this phone with the do not call registry. I still get daily calls from this number. I do not answer. They do not leave a message. This call is coming from Nextel Communications Inc. Silverdale, WA. 360-340-9505 I just want them to leave me alone. I will never use NEXTEL because of these nuisance calls.

I have reported this number to the National Do Not Call List.  I am still receiving calls from them with no voice mail.

just received a call from them with no voice message

Call from this number on June 29 2010 but they left no message.  It is a scam I am sure

Who does this number belong to?  How do I stop them from calling my cell????
