I took 9 days of vacation from 01/10/2017 to 1/22/2017 and didn't get paid for it

Vacation pay is not compensable unless the employer has a contract with you or at least a handbook that provides for paid vacations, and unless under that contract you are covered. Otherwise, you are only entitled to be paid for the hours you actually work.
