Poor service delivery total incompetence

I took out a home loan with Nedbank last year, property was only registered in mid October and the bank set the first debit order date for the 30th of November and I made sure that there is an money in the account for the debit order as the account was new.

On the 30th of November the debit order went through, now I am harrassed daily by their consultants telling me that my account is overdue and I have never missed any payment.

This 4 months with Nedbank has been my worsed experience ever, I have been with FNB for many years and never experienced any of this ****, I regret daily why I didn't accept FNB offer now I must pay registration fees again to move my loan to FNB because I cant deal with this level of incompetence from Nedbank.
