*****sters that debit my acc without any permiasion

I want to know who gave mytechzone permission to debit my account with R150. I want a recording where i gave anyone permission to do that. I am going to take this matter further as i know i never gave anyone permission. I got a mandate and i declined the mandate how could a debit order be loaded if i declined it. I want my money back immediately and i want the recording as i know im going to win this matter in court. No one had any authority to debot my acc
