“I haven’t paid him yet. This is not what I expected when I talked to him about my expectations. I even negotiated the price down to $7k. I dont know how to get out of this.”source ↗
“So I am getting ready to pay and I am questioning the invoice. The bid listed all the materials, and the final bill agrees. However they overestimated the number of retaining blocks.”source ↗
