Unauthorised debit orders

I've cancelled my Afrihost account as result of non-deliverance (router was delivered, but no services was activated and fibre not installed to my property). The courier company fetched the router from me. FNB alerted me of the new debit order, as it is below R100, I didn't receive any notifications. I've returned the debit order, as it is unauthorized. When phoning Afrihost, I was told this is for the router delivery fee. At no stage this was disclosed, or option given to deliver the router to their offices. I will report this to the Ombudsman using my bankdetails not for the intended purpose disclosing this.
