New Account Manager Useless

I received an email from Siyanela Mahobe.Stating that I am in arrears , but I settled all my arrears in July. I have requested on numerous occasions that she contact me directly to which she has not done to date, she just sends a statement and says please see attached, I want to know where does this so called arrears come from? I have also sent emails to advise her that I changed my debit order date to the 25th of every month because that is when I get paid the school I work for does not pay us earlier than the 25th, and since August all my debit orders have been going off succesfully, so why am I bring charged fees when you are trying to debit in dates other than the 25th , like now we haven't even gotten paid yet and you have tried to debit on the 18th then you going to say the debit order was unsuccessful when you are trying to debit days before we even get paid. Who is going to pay for fees when you haven't even communicated with me to enquire when we are getting paid. I work for a private school they don't pay earlier we are only getting paid on the 23rd of December. I will not pay any penalty feea because you are not sticking to the arrangment and my debit order date request.Also you sent an email saying that you tried to call me when as I stipulated and requested I pay the account not my husband , you have never called me on *** I advsied in the email that all correspondance must be done with me directly.
