Disaster Trim

I went to great clips to get a trim about 1/2 inch of hair. I first asked the person that took me (April) if she could actually cut my hair since I am natural. She said yes and trimmed my hair. As she started to trim my hair, she started to take of 1 inch and then 2 inches, etc. I went home very upset and wanted to wait to go back and talk to a manager since I was devastated. I went back into the salon today (Sunday) and told the stylist that I was very upset with my hair cut and wanted my money back. She started to get defensive and said that she told me my hair would be uneven. She never told me this and also insisted that she will make it even after she did the cut. I had a lot of plans Saturday evening and had to cut them since my hair was a complete mess. I have been growing my hair for about two years now and to have someone chop most of it all off is still very hard for me to process. Not to mention she was rude to my husband and I when I came back in to express my concern. I now have to schedule an appointment with another hair stylist to cut off what she damaged. I put my trust in Great Clips and left feeling terrible.
