ask them to change it, and get the name of whomever does it. That way, 2 things happen: it gives incentive for them to be sure it's done since you have their name and if it's not done, you can call and report their name.

When in CS, I always took responsibility for fixing things or whatever and gave my name. It's nice tohave a person to rely on to fix things. I neverhad a problem because I always fixed what was wrong. good luck.
