Nelson Mandela Municipality billing system

Nelson Mandela Municipality billing system need a desperate improvement. Every month I submit my water reading via their IVR system and most months I am billed for more water that what was submitted. I am also chargeda different rate for 11 kilolitres of water. It us a nightmare to get uour accounts sorted out. I went into the Customer Care office today to make arrangements to pay my outstanding rated and was told that I could not as there was already an arrangement in place. This arrangement was done 7 months ago. Now I am told that the arrangement is for 12 months and it ends in November 2024. I am a pensioner trying to make sure that the electricity does not get cut off and all I am told this is what you need to pay. The impression I get when going into these offices is that they are doing you a favour forgetting that we the public pay there salary
