Unable to attend job?

Hi, I’m currently a student and I’ve applied a job with my parents agreed with it. Now I was accepted for the job and they disagree me to go for the job and will not pay for my college fees if I go for the job. What should I do now? I feel very sorry because I had agreed the employee.. any idea how to tell the employee? I don’t want the employee to think that I’m a person who doesn’t keep my promise and blacklist me from the field.
