After replacement: battery warranty

I was able to get a replacement battery installed a few weeks ago at a local dealer (not dealer of sale).

The warranty section at Chevy https://www.chevrolet.com/electric/myaccount/vehicles still lists my warranty as 8 years from date of delivery. The EV concierge maintains that this is a dealer issue; unfortunately, I have divorced myself from them for unfriendly attitude. Moreover, I (possibly in error) believe that a problem will be paid for (parts and labor) by corporate.

Hopefully, this is just an update issue.
