extra deduction without confirming with me

Good day<br> <br> I am very unhappy for the fact that African bank is now deducting extra money from my account . This is unacceptable as they do not even confirm with me whether I can afford it . I have been paying every month my accounts without defaulting . I need clarity regarding this as I cant understand how I can be in arrears if I pay every month on time via debit orders . If someone does not contact me I will take this matter to the Ombudsman . I have send statements requests to your customer care department on the 15th and yet no answer regarding the statements and extra deduction .<br> <br> Regards
