My question involves business law in the state of: California.
A vendor of ours has been over charging us on the cylinders we rent to contain the gases we buy from them. We recently discovered they have been charging us for more cylinders and for longer durations than that was actually in our inventory. This was verified by comparing the quantities in the rental bills vs. the gas bills as they are separate. The vendor already gave us back credit for overcharges for the past year, but my question is if they are required to credit us back even further? Thanks much.![]()
