Temporary Residency

Hello,
I have looked throughout the forum, but I can't find any recent posts that relate to my situation.
6 months ago I decided to student teach/ intern at a private school in Malta. I am a full time student and citizen in the US. Before arriving I tried to extend my visa. I contacted the embassy of Malta, the Consulate of Malta, and various other people. From that I received a lot of different information. I decided to go with the advice I got from the Consulate of Malta- which told me to go to Malta and apply for a temporary residency.
Fast forward to now. I am not here in Malta. I have gone to the Department of Residency 3 different times. Each time I have been sent away. The first they told me I didn't have the correct insurance, so I bought new insurance. The second I was told that I shouldn't be applying for a residency, but rather extend my visa. They sent me to the police station that deals with immigration. When I got to the police station, they said they don't deal with that and sent me back to the Department of Residency. I then called the department of Residency and they gave me a number to call in order to extend my visa (not sure what I was calling). She yelled at me and said if I wanted to extend my visa I would have had to do that before I arrived (which I tried to do). She then told me to go back to the Department of Residency and apply for a residency.
Yesterday I went back to the residency office, and had every document that I needed ready. When I got to the man he told me this is not where I need to be (I was in the non EU line). I tried to explain my situation but he kept telling me to come back in the morning (it was the morning at the time). I told him I didn't understand and then he said it wasn't his problem that I couldn't understand him. He then proceeded to ignore me.
I apologize for this long story, but I am very frustrated and upset with the situation. I only need to stay until January. I understand that with a temporary residency you are supposed to be here for a year, but it seems I have no other option. I have tried to contact the US embassy in Malta but they won't help. I'm guessing I should try to make an appointment with the Department of Residency but I heard that could take months.
If anyone one has any advice on my situation I would really appreciate it.
Thank you!
