ok so I did this lawn renovation the other day. Wasnt able it finish it. Some unforseen reasons came about and I told the guy that I wouldnt be able to finish it, and recommended him to another company. I also gave him a refund for the amount he had paid thus far. We finished roughly half the job. Then he tells me, that I did an unsatisfactory job and wants me to fix it at my expense, within 14 days but does not give me a consequence. Then he writes me this letter and says the same thing and says his refund should be more. He broke it down and said, I quoted two hours for the bob cat only used it for 1, 3 hours labor, only did 1.5. 7 yards of soil only used 3.5, and then 1/4 of the debris were hauled away. The final specs on the job were, 1.5 bobcat, 3 hrs labor, 4 yards of soil, and a 1/4 of material hauled away. He said that I am in breech of the contract by not finishing the job, and that if I fail to fix the part we did do, I am responsible for paying another company to fix it. I will fix it becasue it will be easy. We just have to build up some areas, shouldnt take more then 1-2 hours. I am more concerned about the refund. The Refund I came up with was about $100 his is like 275$. Any advice?
