Watch out for early fee deductions

My son has an Elite account. He is on the Rebate option. My daughter helps to keep his account at the rebate threshold so he can get the rebate and not have to pay the minimum management fee of R69 at the end of the month. However, Standard Bank decided to deduct their monthly fees(Cheque card fee) early, on 30 Jan instead of 31 Jan. This caused my son's account to go below the Rebate threshold and now he's being charged R69. Yes, 31 Jan was a Sunday, but to be fair to the customer Standard Bank should have deducted on 1 Feb, as they've done before. So watch out for early deductions!
