Hello, good evening, my room lost electricity a few minutes ago, and with this heat, can someone help me to see if they can come and check it for me?

Ok. There's a fundamental misunderstanding here. By law every apartment complex is required to have 1) management phone with posted hours, and 2) an emergency number for after hour emergencies (e.g. utility issues, storm damage). Go down to the apartment office and get those numbers. That way next time this happens you know who to call for help immediately. ;)

Go to there website to contact maintenance for your problem.
