Am I wrong for not changing my review after the women made it right?

I'm divorcing my husband and for the people who saw my past post. He's the one who called me a whore when I was wearing shorts trying to help our disabled 16 year old son to the bathroom after he refused to help him since he was working on his car. He called me a whore because I had shorts on with my daughters boyfriend there.

Anywho, my husband decide to be the one to move out. And with him gone even though he wasn't much help anyway I needed help with my son. He got in a car accident that left him wheelchair bound. He can walk sometimes, but some days cause him more pain than others. He does physical therapy. I just need someone to care for him while I'm at work for a few hours. I went searching and found this women. She had her own home health company. It's a small business owned by her and she employs her sisters too and I reached out to her. She ended up being my son's AID to help and we had her two weeks and I fired her. She was honestly less help than my husband. My son I consider to be pretty low maintenance besides needing help to the bathroom since the bathroom is downstairs and help with his stretches and help getting dressed undressed and into the bathtub. Which I'm usually home by the time he may need a bath. Unless he's really sweaty after school she didn't really have to do all that. He's pretty much a normal teenager who will just play video games. I did want her to take him outside every now and then but she didn't have a lot to do. I paid extra to add on house chores which she did about half the time. She wasn't much help to my son at all and the day I fired her she did not help my son at all. To the point he was asking for help to the bathroom and she was watching TV and my 15 year old daughter called me when she got back from cheer that he was upset and crying sitting in his own waste. She got her brother in the tub and helped him bath. This lady also STOLE all our body wash, shampoo, and conditioners. I fired her. And left a really bad review. I think my review hurt her company more than she thought because she reached out to apologize and said she had a sick family members which is why she was off her game those two weeks. She refunded all my money which was about 800 dollars along with reimbursing me for the body wash and stuff. I thanked her and hoped her family member got better. She then asked me if I would change my review and rate her higher now that she fixed everything. I said no. Maybe it's an unpopular opinion but my review/rating was based on the service. Not after the fact. She still gave me one star service so why would I change my review? She asked for a 5 star review since she fixed things and I said no. She said she thought I would be more grateful that she gave me a full refund plus some. I should be grateful that she refunded me money for a service I didn't recieve. My son had to be bathed by his 15 year old sister and was put in an embarrassing situation because she wasn't doing her job. She wasn't doing the chores like she was supposed to and didn't give me what I paid for. I deserved my money back. She wasn't doing me a favor she was doing the right thing. And the plus some was for a bath products she stole. She said she would settle for a 3 star and I still said no. I rated her based on her service which was one star. Just because my bad review is causing her issues which is what MADE her refund me otherwise she wouldn't have doesn't mean I have to change my review. She gave me one star service. What she did after the fact has nothing to do with it. She's upset and now claiming I "defamed her". Am I wrong?
