CDI College review: Accused in cheating and plagiarism

Hi, I am a student travel and tourism course. on January 10, 2020 was an exam on my table I placed just papers and pen my handbag was situated behind me on the chair, I finished my exam handed my papers to teacher, after 10 min my teacher accused me in plagiarism in front of other students. On January 13, 2020 at 8am I was at college for my lessons, but student service coordinator handed me papers with college policy with the words that I am expulsion from college. Where was no warnings, no probation. I am depressed, paid money and dont have diploma. I did not copy or look into my books, or to do that people needs time.I am sitting right in front teacher, if he saw me why he did not say me right the way. In one day they make decisions to determine, I didn't make a crime, didn't fight with any body. Please help me to resolve this problem together. Thanks in advance. My name is Olga Cakir
