Alterations

While the owner, Xia Lee is very pleasant and friendly and the work she did was done well, my complaint is two fold.
1. She didn’t do what I asked her to do.
2. She WAY overcharged me for the simple task she did complete. More than 20.00 over what she quoted me.
I asked her to add a small cuff around the sleeve with the same material I was having added under the arm to make the sleeves fit better. The material was different from the rest of the top so I wanted to tie it in by having a small cuff added of the new material. I also asked her what she would charge to do all of that. She told me between $ 45. -$ 50.00. I thought that a bit high but agreed to that.
When I picked it up today she said «Oh I didn’t add the cuff on the sleeve because I thought it make the sleeve too long.» what?! I specifically asked for That!
I wasn’t happy that she ignored my request but what could I do? I need it in a few days. So I went to pay and she charged me over 68.00!!! What?! To open a seam and add 4 inches of fabric?! (that I provided btw). That was not right. It should have only been about $ 30.00. Ripped off.
