Municipality gives no response - website needs updating

I struggled with their online website to get a payment through with the result they received the payment 2-3 days late . The received the payment on the 9th and on the 10th sent out a pre termination notice for my electricity and rates. I had already spoke to someone who said that they saw the payment on the system so all was ok so to receive this notice with an extra fee on it stating they would terminate my supply on the 24th December was most annoying. I tried calling all phone nos on website but are not correct, eventually getting the info operator who checked the balance and said it was only the current which is due 5th January 2021 but could give no detail so she gave me three further nos to ring which I tried to have them ring constantly and then be cut off. I have no way of reaching them so I left a message on the siyakhokha website to no avail. I emailed the municipality information centre to no avail. No responses have been received. I do not see that I should pay for this notice and I want assurance that I will not be cut off on the 24th December 2020.
