Debting bank accounts when I never took anything

<p>I don't know this company or never received any call from them offering me anything and besides I wouldn't even take anything that I don't need and then today out of nowhere I find a debit order of R251 on my bank account not knowing what its for and the only reference is a landline which says does not exist or is listed as ********** ********** 300. Why is there people going into my account without my consent?? Who are these people and what does your company do anyway?? I am not interested in anything and I don't take lightly to someone going into my account... I need answers very fast so I can take this further</p>
