I regret for joining this useless Standard bank

I am disappointed with standard bank and I went to the brunch with no assist. I paid vaf on the 7 of this month and it was acknowledged and I gave the the new capitec bank account to debit from, but now on the 18 of this month they put a debit order on standard bank and it was unsuccessful and I'm penalised R147 for unsuccessful debit. 1 I updated my banking details long time ago and why they debit at this date is not part of agreement? 2 I am charged R147 for nothing and that was done intentionally by std. This bank is nonsence.
