<prompt>  Human: I dont know if this is the right place to ask this question, but I think I remember seeing it asked here before. That being said, long story short, I was offering guitar lessons over craigslist and had a potential client answer saying she wanted 2 lessons a week for a total of 160 a month. She tells me shell pay for one month in advance and sends a check. About a day after it send she says she has an Urgen Message that the check is going to be larger than it needs to be and I need to send the excess money to her nanny over Western Union. Im not asking if this is a scam, I am entirely sure that it is. My question is what do I do now. I will, upon arrival of the check, have either a fake or bad check from them, I have their number theyve been using to text me, an email address, and the shipping information for the check they sent. Is there somewhere I can file a report where it wont be backlogged and forgotten forever?
