Dealing with bounced Direct Debits?

I have a couple Direct Debits that bounced, and I am not sure how to deal with them.

I have tried tagging them as Payment on Account, but then can’t class them as a refund, to pull the payment back out of the account.

What’s the best way to deal with them?

You can either delete DD entry or record a payment entry and tag it as refund to customer

I was thinking the delete route myself, due to the fact that technically, the payment was never made.

Thanks
