Standard banks system needs upgrade

I've been a prestige Standard bank account holder for many years and have been with Std Bank more than 20 years. I am very concerned not just for the safety of my own account but for all other account holders as its been more than a year now over weekends whenever i withdraw money or swipe my card i do not get an sms at all until Monday ( if it does come through). I cannot trust my balance in my account aswell over weekends as it shows different balances. I have to wait until Monday morning to see what is actually going on in my account. This morning money was transfered from another person. (Also Std Bank) to my account. As far as i am concerened the money should clear and be available immediatly. Which now almost 5 hours later i still cannot withdraw. I am seriously thinking of changing banks for a while now and the only thing stopping me is all the hastle with changing. Its like Std Banks whole system is sleeping every weekend.
