Standard Bank inconvenience

They deduct money off my bank account they way they feel like. This is really unacceptable from Standard Bank. The message that was send out starts with for your convenience but it is really more of an inconvenience than anything else. I don't get paid earlier because it is Christmas break. I still get paid the same day. When I got the sms I phoned immediately saying the same thing and I said I will put a stop order against them if they take the money before the 23rd and this morning I went off and I received a message from my bank saying I need to fund my account today. I did everything that was expected from me. I am once again on the line with the bank which just says sorry for the inconvenience. Why are you so unproffesional. I will not accept just an apology as I need to spent airtime and time from work to sort this out. This is the most pathetic service I have ever received from a bank.
