Cannot count accounts

They've forced a debit order date. So I requested a debit order date change and still no action from the company. Instead I've had accounts department tell me about policy and how debit order is automated, and they cannot change that. But, I've sent them the very same policies they're talking about and there's nothing to back them. It goes against the code of backing practices for them to force a debit order date, because I didn't specify the debit order date.
