Don't you have the appraisal forms, matrix, scale and score given to you?
Has the management issued any communication in writing on result of appraisal and offer of again contarctual appointment?
Is is entirely your choice.
Even after 4 years they do not want you to be a permanent employee.
Don't waste your youth and time here.
Try to clear some exam and be with some good employer and in permanent job.
