I refunded the wrong amount. Is there any way to cancel it?

[djjohnny]

I know I entered a partial refund of $10.00 but Paypal is showing a refund of the full amount. Is there any way to cancel the refund and start over? It is still in "pending" status.

Not likely.

You could try with ungent phone call to customer service, but that should have been your first and immediate action.

Can I cancel a refund?

Once a refund has been sent, it cannot be canceled.

Ask the other person to send you back everything minus the $10.
