I had a tasker hang a wooden shelf and he drilled too many holes in the wall because he overshot the hooks and now there’s a hole on one side of the shelf that’s visible. Really disappointing because I spent $** for him to do it and I feel like I could have done it better myself. Also, he scratched up the wall and left dirt and black marks on the wall so I had to go and buy a magic eraser to get the wall looking back to normal. I live alone and don’t want to anger this man and put myself in danger so I didn’t want to fight with him over it. I didn’t want to give him a poor review because I also didn’t want him to know it was me and get upset. Can I send you images wither holding a piece of paper with the date on it? I can show the hole that I’m now going to have to patch and have someone bring me paint from the apartment complex to match. Just really inconvenient :( any help or guidance would be so much appreciated.
