Cancellation of the unauthorized subscription

My account has been debited under a subscription of R149. I wish to formally request the immediate cancellation of this subscription. However have not found the right email or contact numbers to be assisted with that.

As per prior communication, I was advised that my account would only be debited once I entered into a phone contract. Since I did not proceed with any phone contract, no debit should have occurred.

The consultants I spoke to confirmed that if I did not take up a phone contract, my account would not be debited and the subscription would automatically become invalid. What's surprising is that I declined the offer, but still a debi order is registered.

I kindly request assistance as i would like to cancel the subscription with immediate effect, and demand a refund of all debits made to date.

May I please be provided with the correct email address or contact numbers for the relevant department. I would like to contact them before escalating the matter to my bank’s ***** department.
