When you do correspond with him and send any monies back make sure to put everything down on paper and try to get him to sign all documentation. Unless of course all payments were done through paypal and then you have a running record of it. Signed documents will fortress your case though. Kudos to you.
Yes I have only used paypal with him and will be refunding the money through paypal with an attached note. Thank you everyone for all of your help.
