Dairy Queen review: I am complaining about work done for company without pay.

My Grandson, Wyatt Baas (age 15), got his 1st job at DQ here in Tallahassee.
He was hired on Friday Feb. 5 and his first work day was Sat. Feb 6.
Wyatt worked a total of 24 hours until he quit on Feb.19.
He has attempted to get answer from his manager as to why he was not getting paid with no answer and now manager does not answer any message about pay.
Wyatt said he never got an employee number and entered his work hours on a piece of paper which he gave to manager. Other employees were entering their work time on a computer.
