"I messaged wih someone the other eek but the information I was givenb was fraudulant"

Who  ?    A buyer or eBay ?

" I am still trying find out where the money goes when I sell an item"

As already advised, you'll need to be signed up for managed payments but 

Is the payment showing in your Seller Hub > Payments ?

Has a buyer told you they've paid and the payment's not showing  there ?
