I am in the same boat as AER, let alone the cells were damaged, QR codes scratched off, swollen, etc, they were the wrong studs with no hardware. Not only did I not get the wrong batteries, they are unusable. I see that I need to file a UPS claim now? What is the time limitation to do so? I didn't sign for them, they were just left on my door step. I would like to know what next steps are please.I am working on getting it taken care of but all I can do is pressure the supplier and provide them with the information they need.
