Called my business line and said nothing. After my 100th "hello", I hung up.

Called again on my business line, 3 times in two minutes. Left no message.

Called 12-3-15.    Water Co Serv.   Answered as per usual.  asked for owner by name( was me but lied and said I was someone else)   Asked how I could direct their call.   They wanted the business owner.    I said the business owner is in the TEXAS office this is NC office.     Said I could get the number,  and the lady said OK   so I pulled up FBI website and gave her the FBI toll free number.         Done this to many scammers   never fails.
