Money always leaving the account late

Standard Bank has a habit of maintaining money in my account after I've made a purchase by swiping my card, and I still get a notification. Weeks later I get another sms notification for that same transaction and the consultants tell me that the money is only debited now because the stores had not done their banking as yet. How is that my problem as a client to the bank!? I payed weeks ago and by now I've used up all the money in my account, resulting in my account going into arrears (without my concern, then they charge me extra for those arrears). As far as I know, my account shouldn't be going into arrears at all!! This has been happening for over a year now, since 2014, and I've decided to find a bank that actually has an interest in its clients. <br> I've issued out many complaints about this and all the consultants could say was \Sorry"!!!<br> What's the point of swiping your card if the payment is not immediate and why send me a sms notification with my new balance in the first place if the money is still in my account!?<br> I'm done with Standard Bank"
