Electricity and water Billing

I am sleeping in the dark with no power. The power was disconnected today 21 February 2018 whilst I was at work. The reason for Disconnection was that payment that was done yesterday morning 20 February 2018 "Payment does not reflect on the account. Please contact the office tomorrow" from + ********** 4849. This is the number that I was given for after hours re-connections. Anyway I will wait for tomorrow. How long does it take to reflect. Why doesn't the company notify by sms that they are disconnecting. They send email yesterday and I reponded instantly and did the payment as stated on the email but today . it was a different story.
