We accepted a proposal for a 23 panels solar system and paid deposit, on the day of installation they could only install 22 due to roof space. Was told by the installer that the company would adjust the final invoice by deducting the price of this panel.
They sent me the same invoice and refused to deduct the price of this panel. Couple of email exchanges later I stood still and they advised they will uninstall the system but they refused to refund the deposit back which is $800.
Am I being unreasonable to request the money back for something they didn't install ?
What should I do.
What's the panel worth? ~$150??
