STANDARD BANK DISAPPOINTING!

I am trying to to get Standard Bank to assist me to buy water for my prepaid meter from the Mangaung Munisipality through my internet Banking system but they can't get it right.This has been going on for the last 6 months.I have tried everything from my local private banker ,her superior and several head office departments.I have just put the phone down after again hanging on for the past 30 minutes without anybody to assist in the Call Centre.This has been going on for the past 6 months and when they do answer they ask a few questions,give you a reference number and you do not here from them again.Then after a few weeks you try again and the same story starts all over again.I can buy electricity through the system but not water.On the face of it it should be a simple problem to solve but they can't get it right. Really a sad state of affairs.
