bad attitude, rushed and not a good job

I made an appoitment for 6pm on Friday to have gelish overlay.I arrived at 6.02pm.all the nail technicians were busy.i was told to be seated. I waited till 6.15 another girl came and asked me my name.i asked her if she can find out how long it will take so I can come back. she said I can be back at 6.30pm so I popped out.I came back at 6.30pm and the one nail technician had just finished her client.the mannerism of the girl was not very friendly. she didn't apologize for the wait. she shoved the colors in front of me. the sample of colors are very bad.she made choose a color very quickly and then she suggested I make one nail on each hand a different colour,i was happy.this girl kept getting messages on her phone and she was rushing like mad to get done. in 20 minutes I was finished.when I phoned I was told R200 when I paid they charged R240 I asked why and they said its R20 per nail for an extra colour, they were offended that I asked.i don't mind paying but I wasn't told.i examined my nails and I complained that my nails were not filed properly the girl who did my nails wouldn't talk to me, I was told my nails are short and sorry you not happy.
