Pathetic Service - Standard Bank Vehicle Debit Order!!!!!

Standard Bank have taken it upon themselves to decide when my debit order will go through for December. They have sent through an SMS at 11;30am to advise that for my convenience they will make the debit order tomorrow, without my permission. I called the call center to say this is not possible as i only get paid next week and i am away overseas next week and will require to use the funds in my account - her response was to let the debit order go through and then call them to refund the money (which she couldn't tell me how long it would take - and i leave to go overseas this weekend). She said they can't change the debit order date (TO MY NORMAL DATE - the 25th) because the debit order is set for tomorrow, WHO ASKED YOU TO CHANGE IT TO TOMORROW?!?!!? Why only advise me the day before!!!!! This is absolutely pathetic service as i have now been put under unnecessary stress when i have planned my financials accordingly, they have no right to make these decisions without my consent!! I am extremely frustrated with this and find it a major inconvenience to now have to withdraw my money just so they don't debit my account!!
