I was scammed, how do I get my money back

if I was scammed selling something on Facebook marketplace and for some reason I was required to send money to Zelle cause they needed to create a business account and they overpaid so I needed to send the difference back before I received my payment, at first I thought it was legit but then they kept asking me for more money but I did pay $550.00 through my Apple Pay account trying to accommodate their requests but it gets worse so I just want my money back, they already have the iPhone 11 I tried to sell to them but I do not have my payment so I just want my $550 back they can keep my iPhone but i want the money I sent back. I was hoping apple would help me out with that.

V/R,
