Double payment via two different pay methods

On the 1st attempt, Ebay's Afterpay failed to complete the transaction with an error message while it was still registered in my Afterpay account.

 

On the 2nd attempt, I used PayPal to complete the transaction.

 

The link https://www.ebay.com.au/help/home that shows my recent orders has the following options for a particular item

 

Tracking your item
How buyers can cancel an order
Get help with an item that hasn't arrived
Return an item for a refund
Contacting a seller
 

I don't see in the option selection for double payment issues. 

 

Any solution?
