I recently had a new roof installed. I paid the $1600 deposit and paid the remaining $4800 roughly a week later when I received the invoice. I paid the total amount on the invoice.
Last week, I had the same company come out and give me an estimate to replace my windows. I signed an acceptance of proposal and yesterday they came and measured to place the order for the windows. Two hours after he left, the billing manager calls me to tell me she forgot to put a $675 charge on the roofing invoice for the gutter guards and we still owe it, even though we paid the amount on the invoice and she admitted she forgot to add it.
My question is this: is the acceptance of proposal legally binding for the windows? Because if I pay them the $675 I’ll no longer have the full amount for the windows. Can I get out of the proposal?
