If a scammer ends up bothering you via the phone, on the second call be all excited and say, 'the authorities have asked me to record this phone call - okay, what do we need to do next?" And I'm guessing they will hang up darn fast and not call back again.
Here is the last email sent by this scammer, with all the usual blah blah blah about their fake story to try and rationalize why they would be overpaying by so much (and of course leaving out the crucial details of ALL of their money is fake, the shipper is fake - there is no shipper, there is no husband, and the only one who gains from this is them, when they receive the victim's good money via Western Union so that once picked up it is untraceable).

Subject: Re: Overpayment..
Good to hear you have received payment for "Curious". Thanks for your update, I am very excited and can't wait to have your work in our home. I hope to give it a very good home and enjoy the piece for years.
Regarding the payment, my husband overpays you because he didn't have full details of the transaction since I was sick when he sent it. He mistakenly added mover’s payment with yours. He sent you a check of ($6,200 instead of $4,500). Anyway that should not be a problem, kindly deposit the check with your bank and as soon as you are credited with the funds, you can go ahead and remove the asking price for ("Curious") and forward the difference back to my husband. I will talk to him and get back to you with the information require sending the refund back to him.
Meanwhile, the shipper is currently on Christmas holiday. I was able to get in touch with him shortly before sending you this message. He said he can not come for the pickup now until after Christmas or first week in January 2012 which I think is still very ok by me. He has promised to get in touch with you to arrange for the suitable date and time with you. Try and make shipping arrangement with them and keep me posted with updates.
Finally, I would like to thank you for your patient and sincerity. I hope to purchase more of your works in the nearest future and meet you
