A chargeback is a civil matter not a criminal one. Unless you can PROVE BEYOND A REASONABLE DOUBT that the person conducting the chargeback intended to do so from the outset in order to defraud you, this is not a crime.
If they do not return the item, MAYBE, there could be some possibility of a crime report. Maybe.
For the most part, the police are not going to investigate this even if they do take a report. The best you might hope for is that they give you a case number and you might be able to write the loss off on your taxes since it would be a loss, I presume. At least the business owners I know are able to write off certain types of losses ... but, if you are doing your sales on eBay and the like, you may want to consult a tax professional to determine what you can or cannot write off.
