OK so this is the issue - my client has IPS Commerce for subscriptions using Stripe; two transactions have been flagged for manual approval, however these do not look like genuine subscribers as Stripe has flagged them as an elevated risk.  What we would like to do is get them off the system, but because we are new to this type of issue I was wondering do we Void or Delete these within the commerce system.  Image below shows the options:

Void. 

You don't want to delete all traces of fraud, but rather stop the transaction.

@CoffeeCake Magic - thank you 🙂
