Thompson fencing and deck repairs

I found this provider on Angi. After the initial on-site visit, I received a quote of $6076.50. After asking a few questions I was told the quote needed to be revised as the Brian's fiance, Tiffany, forgot to add screws, etc. Received revised quote of $6686.50. After some additional questions about listed materials it was determined that the quote was based on 6 ft pickets. I requested 8 ft pickets on the Angi website as well as during the on-site visit. I used the word "stockade" as I had been told that this is what 8 ft fences are called. Tiffany stated that this was an old word and so the quote was revised again to $7358.67. She also stated that she saw nothing of what I input on the Angi site. Tiffany asked for a $3000 deposit up front. Gave her $3000 cash on 4/17/25 and she added to Angi. I did not sign a contract but do have a quote for $7358.67. Tiffany stated to me that there wasn't a contract to sign so I assumed the quote was what we were working off. Brian started the job on 4/22/25. There were immediate issues such as him making a wave in the fence because there was a large root in the way of the next post. He moved the fence back from the line to avoid the root. He did this without asking me first. He showed it to me afterward. When I took a good look at it and complained he came up with the solution of adding pieces of 2x4 to the post so that the fence could be moved out and make it straighter. He was supposed to move the 4x4 post to one side of the root to get the fence back in line and remove the piece mill 2x4s. He dug a hole but never moved the post and now I see that the hole is filled in. This section of fence waves in and out from beginning to end; approximately 100 feet. There have been numerous issues with the pickets being slanted to one side or the other; not straight. They have been removed and straightened but some still don't appear straight. Some of the 4x4 posts have warped and moved the fence. This may be from leaving the posts for MANY days until the horizontal 2x4s and pickets were added. The fence on the left side of the backyard is supposed to attach to the neighbor's fence at the end of the yard; it does not. It's about 8 inches off. The fence on the right side of the back yard has similar issues. Some of the 4x4 posts have warped. The pickets were supposed to be lined up with an existing section of fencing but they don't. A broken piece was supposed to be removed but wasn't. When I pointed it out Brian removed the broken picket but did not replace that picket so there is a gap where the horizontal post doesn't meet the 4x4 post. As stated above, Brain started the job on 4/22/25. Per Tiffany, it was supposed to take 1 week. Tomorrow (7/22) starts week 14 (FOURTEEN). Typically, when Brian shows up it is late morning, i.e. 11:00 AM and he leaves around 2:00 PM. He has not worked at my house for a full 8 hour day EVER. He comes a couple of times a week for a couple of hours a day and then I don't see him for a few days to week or more. I never hear from him or Tiffany unless I reach out. If I call, I get a text message back. They often tell me that they will be here and they never show up or that she will come over the weekend to install more pickets, but she never shows. At this point I still don't have a single portion (wood, chain link or vinyl) of the project completed. I am not happy with how long the project has taken nor the quality of the work.
