This number has called my cell phone 10 times in the past three days.  I don't answer and they don't leave a message.

I called the number, there was answering system saying:"Thank you for calling corporate office, Please leave a message and someone will call you shortly"!!

I just got a call from this number and they hung up without talking.

Hi... this phone number calls me everyday and it's annoying.  I have not answered but dont' know who they are.

I just got a call from this number, and they hung up without talking. Unaccetable.
