debit order

<p>MOney is deducted from my bank account as a debit order that I did not arrange, The bank advised its a compnay called bus on line tel no 011- ********** . But no other details. When you get thru to that number. The ask for a name you must type in which I dont know and then it cuts you off. How can a bank deduct without your authorisation. The money was reversed, but I have to check every month and do the reversal which costs R50 per transaction. Who is bus on line?</p>
