Horrible Uneven Microbladed Eyebrows! Huge Regret!!

Same old story as many others who turned to microblading to gain confidence and those who were tired of doing their brows every day for years. Waited a couple years to actually trust someone to do my brows cus I was always so afraid that it would go wrong somehow. Well, IT DID. In a major way. It's been over 6 months since my touch up that I wish I never went for and I still hate my brows and struggle everyday trying to fill them in and even them out with pencil and brow pomade and whatever else.
I trusted a girl I worked with and had known for years who was now also doing cosmetic makeup. A good friend refered me to Eunice and since I had known her for 9 years, I truly trusted her. Saw some pics online of supposedly her work and was sold. She charged $400CAD and that included a touch up. In retrospect, now having googled for hours upon hours and having done so much research, I know why she did such a horrible job. For one, lack of experience in general and with different face shapes/types of skin. She used a cosmetic tattoo machine on me for the initial appointment and kept talking about needing a base first as I had almost no eyebrows. FAIL. I didn't want a base of color, I wanted natural microblading. Which I was so specific about. She made my brows way too close together. They were also two different shapes and not symmetrical which was prob my number 1 complaint. She used a terrible color that didn't match my brow hair color. And she didn't actually microblade. I pointed out my concerns to her when I sat up and saw what she had done. She assured me it would heal and look "super natural" which of course it didn't. I left slightly horrified but as they healed it did get better and I should have left them at that although I still had to fill them in and make minor corrections.
The touch up was awful. Eunice assured me she would do actually microblading and add hairstrokes and my brows would look great. She did the microblading but they got even more close together and way more asymmetrical. She was talking on the phone while doing my brows this time and her hairstrokes were WAY too close together. She didn't know what she was doing, and again assured me they would look great when all healed. They did not. They looked amateur and horrible.
I ended up telling her the truth of how I felt and how disappointed I was and they were not at all what I asked for. I ended up asking her for my money back and she eventually only gave me 50% back and she said that was generous. She also called me a b!tch in the etransfer message when she sent me the money. Eunice claims she made no error and she tattooed the shape I wanted. She has never admitted that she did a bad job or messed up. I am so resentful for the way i was treated and more so the fact that she had the audacity to butcher my brows when she didn't know what she was doing. She has continued to stay in business (and has upped her price!) and seems to have gotten better at microblading so I guess my face was practice for her which is just dispicable.
I've tried to use a retin-a cream to fade my brows and they have faded a lot since I first got them done but it now takes me longer than before to get ready and I hate taking pics...all I see is sharpie uneven angry bird brows. I would have been much better off with my awful but natural barely there brows I had before.
