Electricity disconnected

My electricity was disconnected yesterday at about 13H30. I pay electricity with a stop order that goes through on the 15th of every month. I was surprised when I found out that it was disconnected, since initiall I thought it was load shedding however they later dropped of a note to explain that it was outstanding funds. We then in the morning paid the account as soon as the office open at 7:30. O paid the account at Martin west on Anton lembede street Durban.It is now 20:15 and the electricity has not been reconnected. This is two days now no power we have three fridges which have defrosted and goods been damaged. We will have to bath in cold water. I would like a swift solution to the problem as I have always faithfully paid my bill and will continue to do so.
