3rd time lucky?

I went to Absa Birchleigh about a week and a half ago to change the telephone number that I use for internet banking. When I asked the lady before I left her counter whether the number has been changed, she said yes. However, later in the week when I logged into Absa Ineternet banking, the number was not changed. Yesterday, I had to once again go to Absa to rectify this problem. Low and behold, there were workers working and the lady was \scared"that something might \""fall\"" on me"
