Unauthorized debit.

Last month I received an sms saying a debit order will go off on my account and provided me with the number to call for queries and a website. The number was not working and the website did not exist. I immediately called your contact center and the agent told me there is nothing they can do. i told it is ***** and she said they do not have a ***** division. I asked to speak to a manager who also confirmed that they cant do anything if the debit hasn't gone off. I told him its *****, so capitec waits for the ***** to take place and then to something about it. i left it, a debit order went off on the 20th Sept and i ad to go to the branch to reverse this debit i didnt know. my petrol, my time and bank charges. The lady at southgate branch was very helpful called someone who said, a debit order is between me and the people that debited and they cant help me. she then gave me a number to call to trace the company that debited my acc. I called the company and they told me a lady called and i gave consent i asked them for the proof of me doing that, to date i do not have that and i know for sure i never gave them any consent or any of my account details. Today i received another sms saying a debit order is going off my account month end, different number and a different website but the website does exist this time around, i called the number its not working i found another one on the website called and they gave a number for another company which doesnt work and again i never gave out my details. My thing is as a bank i have a contract with you, how do you allow a 3rd party to transact without my consent? shouldn't they submit something that has my signature as proof of an agreed transaction? how do these people get the account details because i can see i am not the only one. What is Capitec doing about this? This debit is gonna go off, i will be charged for reversing it and i have to waste my petrol and my time going to the branch to reverse the money? I do not have ANY debit orders in my account and please make sure NO debit order goes off my account please. The only debit order I will have will be for my home loan if I ever have one otherwise NO debits are to happen in my account.
