Standard Bank will never see me again!!!!!!

We have been out with my family at Spur tonight and both our cards was declined due to insufficient fund when their was sufficient funds in both accounts, only to have strangers pay for our account. When I finally got hold of standard back they said it was a technical error on their side and if I have tried it now. After the people paid for us. I find this totally unacceptable and I will be closing my account as soon as they open their doors!!!! I can not believe this is how they treat their clients!!! They could at least let their clients know they have a technical error and that they are working on it and not let their customers embarrass themselves in public!!! To make matters worse I was out with my three year old daughter that doesn’t understand this! I am disgusted with this situation!!!
