Edo collection unauthorized debit order

There is an unauthorized Edo debit order that keeps going off my account, went into a branch they said they Cannot help as there is a new feature on the app. But on the app this edo collection doesn't even come up as a debit order. Called FNB customer care numerous times never once got through I'm always on hold but take my airtime. I want this debit order to be removed and blocked but FNB proves they are unable to help I am done with FNB poor customer service, would rather switch to another bank with a better Customer experience
