Very annoying calls with only VOIP caller on their ID.  Calls frequently but does not leave a message.  I tried to call them back twice.  First time got a hang up, second time my call was answered.  They are soliciting HARP mortgages which I have no interest in getting nor have I applied for any loans.  I told them to remove my number from their list or I would file a legal complaint.  They asked for 48 hours to process my request.   Let's hope they honor that .
