Debit order date changed

Just spoke to Wesbank consultant as my vehicles debit went off today and not as normal. Now this is the second debit order went off before my next salary. This makes holiday trip very difficult as I need now to borrow money untill payday. Not very professional for them to decide to move my debit order date. The excuse from the consultant is that majority of clients getting paid earlier in Dec....well I am not part of the majority. If this is the way to treat your clients, I will never ever approach them for finance in the future, even if they offer the lowest interest.
