The Chore Guy

It was obvious his repair work had to be redone before he left and he admitted that. He refused to complete the work unless we triple the agreed amount. He demanded and got compensated for his time and material. So I spent $ 300 and got 1 pressure treated wood fence post, 1 4-​feet rope, 2 1-​ft wood stakes that I can reuse/​recycle later. (I was surprised to learn that his rate is $ 75/​man-​hour and he spent $ 70 on material).
Our fence was leaning. A reputable fence company said up to 2 posts need to be replaced and some posts leveled. Ryan agreed. They both have great reviews. We picked Ryan even though his price was higher because he was available immediately. During his work, I stayed at home and checked a few times with him to make sure everything was ok. He also came in house at times asking for water, restroom and etc. He never mentioned he had any problems. When he told me the work were completed and demand payment, I was shocked to find out that the fence was still leaning as before. (See prior and after photos). He replaced 1 post. He put rope and 2 little stakes to support the new post he put in. It looks weird and even then the new post was still leaning as before. The only other choice he gave us was to pay him another $ 750 to replace 3 additional fence posts (The total would be well above $ 1000. The other reputable fence company said our fence repair should definitely not more than $ 390.) We decided to give him the money just so he can leave. After he left, we found the fence panel next to the new post was broken. It looked fine before he started.
And, his actual start date was close to others because he had to wait for miss utility to tell him ‘there is no utility line under the fence’.
I (a very unhandy woman) dug around the fence posts and found a. The new post Ryan put in is in loose soil, no gravel or concrete. b. 1 and only 1 additional post is bad (very bad) and need to be replaced. So changing additional 3 would be unnecessary. I will update later what is the actual cost we have the repair work redone. But even though my fence may fall anytime, I do not have any strength left to hire anyone else now because I do not know what I did wrong this time.
