STANDARD Worst Customer service.

Our company's online product sales rely on STANDARD's MyUpdates email notifications, which have been offline for over a day now. Despite sending three emails since yesterday to my branch, accounts manager, and Pay alert Branch, I have not received any acknowledgment of receipt or assistance from anyone in STANDARD. In a country where service delivery is lacking, it is unacceptable that Standard Bank has failed to address a global MyUpdates service failure promptly. Thousands of customers rely on this service, and its failure for over a day is a complete failure to deliver on promised services. Furthermore, their business assistance is only available during normal working hours, and there is no support on weekends. This is the third time in a year that this has happened, and it is by far the worst service I have experienced among other top banks. Shouldn't the MyUpdates pay alert team at least reply to my mail? We deal with many banks, and at present, STANDARD is at the bottom of the list of trusted banks.
