My supervisor is very hard to reach and meetings keep getting cancelled — what should I do?

My situation:n

• Two supervision meetings in four months — both rescheduled multiple times
• I am struggling to make progress without regular feedback
• Not sure whether escalating would damage my relationship with my supervisor

nnQuestions for the community:n

• Is it appropriate to contact the graduate school or department?
• How did you raise it with your supervisor directly without it becoming confrontational?
• Are there formal processes for this that I should know about?
