Is this a scam...Craigslist housekeeping ad?
So about two weeks ago I saw an ad on craigslist asking for an housekeeper and I responded I got an answer from this woman named Lisa and she told me that I got the job and all I would have to do is tell her my name and address for her to pay me and I stupidly did and she sent me a $2000 check telling me I have to send 1,800 to her painter through Western Union and then keep 500 and then she's going to send me the address of her house for me to clean it.now I haven't deposited the check on my bank account because I feel a bit fishy about this check.it says it's from wuertemberger dairy LLC which I look up and it's on google which probably means it's real.I'm just wondering why didn't she interview me or hasn't given me the Address for the house.plus she said she got an alert the check was deposited and I know she's lying cuz I haven't deposited it.i just want to know if this is a scam.plus the person Adress I have to put on the western union that it's being sent
to is an Oregon Address,like how do you have a painter working for you in New York but he lives in Oregon.this is all too confusing
If it is a scam what should I do with the check and the lady
