Affiliate Marketing Secrets

My senior year in High School (im currently a college freshman) I created a short film with another guy. This dude was failing the class *radio-TV* and the teacher told him in order to pass, he MUST make a video. So he approached me and asked me to work with him on something. He came up with a plot that STUNK. I decided against it, and I , i repeat, I wrote a new story and showed it to him asking would he wanna do that. His exact words were “I don’t care”. Long story short–I just wrote a screenplay based on it and copyrighted it. I’m fearful he may try to sue me claiming it as ‘his’ when he BARELY did anything with the youtube version. I did all the work. I just gave him all the credit so he could get a good grade, but he never wrote anything. At least not the final product which was ALL my ideas. There is nothing in writing saying he wrote the story. It’s basically just word of mouth. There’s not even a script based on it, it was all improv when we filmed it. So he has no solid information saying he created it, because all he really did was reap the benefits off of my hard work.
I’m also afraid because he’s a very violent gang-affiliated guy. It’s not worth getting killed over. So who’s the rightful creator? Me or him?

I have received multiple phone calls from a fraudulant company saying that I owe them money (I have already verified that I do not, as they said they are a debt collector for Cashnetusa.com. I called the actual company just to make sure there was nothing wrong with an account I had opened up previously. They said I was in good standing and that other customers have complained about the same type of phone calls, but it is not in any way affiliated with cashnetusa.com). I have all proof, etc of this. I was told I needed to pay back $400 that I supposedly took out in July of 2009 (which again is crazy because I did not even know there was a company called cashnetusa.com at that time). Anyways, I know that some people may suggest that I stop these harrassing phone calls by either getting a new number or blocking their calls. However, not only are they calling my work, they’re calling from multiple different numbers from area codes all around the USA. In addition, they have my social security number, bank information, and other personal information. I have put an alert out on all three credit bureaus and filed a complaint on the FTC. However, I went to file a police report as well and they refused to do so. I even explained to the police woman that not only do these scammers have my information, but they’ve also threatened to come after me. In the man’s exact words, “I will personally come after you and make you pay for this money you owe.” Please remember that there is no money I owe in the first place. These people also say their names are Mary Smith or Mike Miller, yet have the strongest Indian accent when they speak. I told the police that I’m concerned because I’m not sure where they are really located and they have access to my personal information so can find me at home and that I live alone so it is something that concerns me. She told me the best thing they can do is if someone who looks suspicous shows up at my home or work then I should call the police. She didn’t even let me file a report for my stolen information! I feel like this is completely illegal. So I have to wait for these people to either come find me or use my information to steal from me. What do I need to do?
