Disgusting behaviour from Eskom Temba office

Called their call centre on 16 October to close my Eskom account but to date I'm still getting billed. I fall under the Eskom Temba office in Pretoria. I disconnected the supply from the meter box as I'm no longer using their services. I have been calling the Eskom call centre every week to get update since October but nothing has happened. Surprisingly they came to my meter box and put stickers for disconnection due to non-payment. It's now complete 3 months being taken from pillar to post. I need to get my final correct bill so that I can pay and get my security deposit back.
