Double GuardMe debit and pathetic service resolving it

First I get an app notification that the GaurdMe debit order could not be done... Then you double debit for 'GuardMe'.

I logged a complaint on the app and then got an email from "FNB Premier bankers" about how to log a dispute.

Seeing that this is an FNB debit, this is unacceptable, refund me, or else I'll cancel the subscription...
