First of all are you in a shared dorm or something? second if not and you are renting a apt unit from a rental agency you are intitled to you're space privacy and rights and your unit is should only be entered becouse of an emergency and inspections do not fall under that..every tenent must be issued a written 24 or 48 hour notice before entry is legal once this notice is served placed on your door or in your mail box then no matter what they are ok to come in..That is law, when i was the maintnance mng of one apt unit before we knew someone had died in one of our units becouse of the smell you will never forget the smell, yet we could not legally enter that unit until we had one the permission from the familly or had secured a possible death warrant to enter..These are facts so i dont know your situation all thogether but seems to me they were wrong for entering unless you agreed to your form of communication being that of e-mail..Peace
