My join is not working

I have three tables the phones table which has these fields(users, numbers, offices and id). The offices field is a foreign key which references the id field in the offices table. The offices table has these fields(names, id and departments). The departments field in the office table is a foreign key which references the id field in the departments table. The departments table has these fields(names, id). I want the query to return the results if the user enters a department or an office or a phone number
