Central Nebraska Bobcat - Chris Riskowski Buyer commited Fraud on Amazon Grand Island Nebraska

I am a seller of wall clocks on Amazon and on February 5th, 2025 I sold Chris Riskowski 2- 10 inch Bobcat E88 Compact Excavator Wall Clocks.  I accidently shipped 1 and he received and let me know he didnt get the 2nd clock. I immediately sent the 2nd clock and both have been delivered says the tracking information that I have and from his comments saying he received them.   He filed a A-Z claim against me on Amazon and wanted a refund claiming he didnt receive the clocks. I supplied Amazon with proof of his comments saying he received them and also the tracking information.  Amazon refunded him anyway in the amount of $70.92.  So I emailed Chris Riskowski if I could email him a pre-paid shipping label to return the clocks and he said he already sent them back, they have never been sent back. He lied to Amazon and to me and knew how to use the Amazon A-Z claim system to get a refund and get to keep the items he purchased but ultimately didnt pay for.  I have waited 2 weeks after he said he sent them back just to make sure that they arrived, they havent, nothing has been returned by Chris Riskowski.  Now he will not respond to emails and Amazon even sent me a rude email to let me know not to say anything to him so I am letting Central Nebraska Bobcat that they have thief working for them and they should handle this accordingly.  And just so Central Nebraska Bobcat and Chris Riskowski know, I will be filing a fraud report with the local Police Dept. In Nebraska so that they can investigate this person.  I am sure I am not the only seller that this has happened to.  I have all receipts, emails to prove what I say and I may not get my clocks returned to me or my $70.92 returned to me but he deserves what I am doing and this will not go away because I cannot stand a thief.
