Bofia Braiding Salon Suzy advertisted a set price for hair style and spoke to her on the phone about the advertised price, charged more after hair was done phoenix arizona

On March 30 I went to Bofia Braiding Salon to recieve services for my hair to be done. The company posted an advertistment on craigslist for tree braids for $80.00,on March 29 I  called to set an appiontment with them and spoke with Suzy whom I asked was she still running the special she said yes. I then made an appt. for tues. March 30 at 9am. When my hair was done I paid her and she told me it wasnt enough that it was $280.00, so I said to her thats not what your ad said and I called and spoke to suzy about it and she said yes. I could not find the ad while I was at the shop so I paid her the $280.00, when I got home i reshearched more for the ad which I found still posted on craigslist, I then text her with the link and she in returned text me back and proceeded to tell me I was right and she apologized to me. I then ask her about fixing the situation because it was completely unfair to me and she never replied. I would like to handle this to the fullest extent because I feel like this was a complete scam on thier part.
