How often do employees get raises at Kibo Commerce?

I worked at Kibo for over a year and I was tricked into a raise. I'm African American. After the change of leadership I suddenly had two white female superiors. One a direct manager and the other a director. People said they knew each other out of work. I don't know. All I know is one hired the other. They asked me if I wanted to be a point of contact for new hires because I had excellent numbers. They said all I would do is answer questions. They were giving an additional $.50 cents for this. I had to sign a form. When the job duties were finally uploaded in the system they had lied. They had taken the white managers job duties and pushed them down to me. Not only was I responsible for answering questions, my job evaluation and job security was suddenly tied to every other associate meeting their metrics. They had, in fact, made me a manager for $.50 cents. When I realized I had been tricked I went back into the office and asked them to cancel that agreement. They refused.
