You can cancel a pending PayPal payment if you do so before the recipient accepts it:
Log in to your PayPal account
Go to the Activity menu
Select All Transactions
Find the payment
Click the Cancel button next to the payment details
Confirm the cancellation
PayPal automatically cancels pending or unclaimed payments after 30 days and sends the money back to the original payment method.
This is not O2 and we are all customers here similar to yourself and cannot answer account type queries.
