Poor Experience with Standard Bank

On Saturday afternoon my payment was declined at the Pick n Pay till. I had more than sufficient funds and had t leave the queue while I phoned the Std Bank call centre to find out what the problem was. I was on the line for 20 minutes waiting for someone to answer. I phoned back a 2nd time and had to wait 5 minutes before someone answered to be told that there was a technical glitch and that there was no problem with my account. The issue is the inconvenience, cost of holding on the line with no answer and that the same thing happened the week before at Builders Warehouse. The simple issue is that you are not dealt with individually but as an insignificant client even though I have a private platinum banking account. Standard Bank needs to jack up there systems and understand customer service.
