I'm using localbitcoins,still did not received anything from seller,i decided to open a dispute

everything im involved in can never go smooth lol

localbitcoins

So today i made my first ever payment for bitcoin via paypal,i sent the money but seller said i have to wait 2 hours for payment to complete.
Im a total beginner in this so i want to know ur opinion,am i safe. Is a dispute needed? What happens when a timer runs out?
Thank to y'all
