Bad service no customer etiquette

Where do I begin?... My first time experience was terrible where my fingers were roughed up to a point where I was bleeding, my cuticles were hurting for almost two weeks. Second experience when soaking off the gel on my toes same thing happened, my poor toes got roughed up and one of the technicians who was doing my toes notified me that I was bleeding. While doing pedicure I could see she is not covering the entire nail when applying the gel nail polish and I told her about it, and I ended up thinking maybe I was tripping only to see when I got home no man I was right she didn't get the entire nails on some toes. Then to top it all the acrylic nails are lifting after a week. I went to the salon on Saturday(because I work during the week, plus it's the day I noticed that they were lifting) to get them fixed. The nail technician app**** gel base but they were still lifting. She tried filing them too, but they were still lifting. After that they tell me I have to pay for fixing because of a 7 days fixing policy and that I came on the 8th day. That the color I had on is not even available anymore. 🙄 Does it make sense and is it fair for me to pay a week later for something that is supposed to last 3 to 4 weeks without lifting? To me it clearly says the quality of products/work was poor and why should I have to pay twice because of poor quality products/work? I don't even know why I went the second time after that unpleasant first experience. Oh and appointments are just a formality they mean nothing. Once bitten, twice shy!
