Serenity Hair Salon (Brian) Very unprofessional and rude. Sherman Oaks California

Last August 20, 2020 I went to their salon to have a hair cut and brazilian blowout. When I went home and washed my hair, it did not change anything! I messaged Brian and sent a photo of my hair and told him that nothing happend to what they did to my hair. He called me and he wats me to go back at 9pm when I have a flight going to Utah. I explained it to him that I can't go back to the salon that late and that I have so much stuff to do because I was so busy that time preparing for my bestfriend's wedding in Utah. I asked him if I can go back on September 8th since that is my flight back home. But our flight was cancelled last minute because of the covid19 in LA.

We decided to stay two more weeks and be back in LA on September 20th. I messaged him if that will still work for him to redo my hair and he said that "I am taking advantage of their courtesy." So I messaged him back that I messaged him nicely so I am expecting him to respond nicely to me. And if it is a NO then NO and if it is a YES then it is a YES. That easy! There's no problem with me if they can't redo it anymore on 20th but the way he talks was so rude and very unprofessional so gave them a bad review on google. I paid $400 for nothing, I was asking for a half refund of what I paid but he messaged me that he already repoted me. He is very rude and unprofessional!
