$2700 Chargeback Opened 450 Days Later for a second time!!! Shopify doesn’t care!!!

We verify every order over $1000 since we deal with higher end devices. He opened it for "item not as described" which is notoriously hard for sellers to win. We say, ship it back and we will refund you. He says there's a swollen battery he can't return it to us via mail. We’ve shipped tens of thousands of batteries and never had anyone tell us we cant but this guy starts quoting ups and lithium rules. So we open an ups hazmat. Nope, he says the managers still preventing him. We call and talk to the manager and he says the customer claimed it was smoking and sparking. He's setting up a narrative. So he on his own then contacts "Americase" to help strengthen his baseless claims. He has Americase write us saying he can't ship it. I contact them as well and they say he was trying to convince them to write the email which they did. At this point, I opened a fraud case with my local police department. I tell them they're now involved in the case. They apologize and say he was trying to manipulate the situation. They write an email that I use as evidence against Kyle. They give me the box for free which I ship directly to him. Guess what, he claims ups still won’t take it. UPS says he never showed up. So, my chargeback response has a police report, America's rep, ups rep, hazmat rep, etc. and guys I actually won! It was a great feeling. But how, 365 days exactly from when the chargeback was found in our favor and 450 days since the item was received the somehow has opened another chargeback. I contact Shopify and it’s a joke. From all research this should NOT be possible without some special situation. Shopify agrees but say I need to treat it like a new chargeback and even through its duplicative will not close it! Shopify doesn’t care about your money and doesn’t go to bat for you when you need it. If any of you have any advice I’m all ears. Ty in advance.
