ToughSystem Limited LifeTime Warranty

This warranty seems a little tough to pin details down. I have the OG V1 ToughSystem 22 inch Small Toolbox that came with a battery tool set that I got in 2016 or 2017. It supposedly has a Limited Lifetime Warranty.

Home Depot link is still up: https://www.homedepot.com/p/DEWALT-TOUGHSYSTEM-22-in-Small-Tool-Box-DWST08130/207205062

I'm having an issue with it and their service department first tells me that 'We have confirmed the information provided, and unfortunately, this product has been discontinued, and we don't have any replacement model for it.'

When I pointed out (very politely) that there is indeed a current 22-inch small toolbox, I got this response:

'it is covered with the warranty as long as the product is still being manufactured however since it is already discontinued that is where the limited warranty ends'.

That is not stipulated on their warranty explanation anywhere on their site. I asked to escalate the issue. I even had ChatGPT double-check the warranty and it came to the same conclusion as me that a discontinued item isn't specified to not be covered (I know, it lies and makes stuff up but it was a second set of eyes that wasn't me asking my wife to read a warranty on a Sunday)

Anyone had this issue and had any strategies to get a replacement?
