System glitches

I have a problem with you Absa bank. Debit orders tracking can take up to 3 days, however with you on the first day the debit order starts tracking my account and there is no available funds you charge me unpaid debit order fee. Ethically so you should charge this fee after the tracking has ended and i had no funds. My debit orders that track my account are always paid but youd charge me for not having the funds on the first day the debit is tracking, second day etc... This is morally wrong - because I end up paying

Please fix this glitch in your systems
