iTunes forgotten account linked to PayPal

[Sparty6969]

I was charged for something I can't remember and it did not show up in my ITunes account. I put in a dispute and was turned down. How do I call PayPal to find out how I got charged and what account was used?

[Whac-A-Mole]

I dont think Itunes accept Paypal payment,the last time I used it for last month?
