Unauthorised debit orders

There are people that are debiting my account without my aithofisation. I have blocked and disputed the debit orders but every month they use a differant reference number.

I have complained at the branch about tgis but they said tgey can't do anything.

Every month 3× R99 is debited from my account without my consent. I don't know the people and my bank can't do anything.

Our information are not safe with this pathetic bank. They can't protect their clients.
