Every month its just issues I am so sick of this

So today I get an sms to say I haven't paid my account for 2 months who told you to stop debiting my account on the last day of the month as initially agreed upon every month its something else you are just doing whatever you want to <br> <br> You will not just debit whatever amounts because I have not told you to stop debiting my account I don't even know what the heck is going on in my account,<br> <br> I am escalating this to the Banking Ombudsman I am sick of this **** ever since I changed my bank account over to FNB I have been having endless issues and I used to sing FNB's praises and still thought they were the best bank out of all the banks.<br> <br> Who told you to stop debiting my account? Make sure that the normal amount as agreed upon is debited at the end of September because I am escalating my complaint I am sick of this ****!<br>
