Disappointed

I am so upset with the service I have currently receive at Standard Bank. Having Banked with this company for over 15 years but what I am getting now is really not nice. Since begin of the year I had to deal with a ********** on my account. Now today I send money to people, my account show that uncleared transactions( meaning the payments never happen)So than I have been told to wait 24 to 48 hours but this don't make sense at all. I have requested for this to be canceled and they can't do that. I am really dissatisfied with standard bank, but most upset because after all the years I am considering changing banks.
