Pathetic service-billing

My account fell behind after I changed my bank account and Absa had not updated their system on time. I was given an account by Vodacom to pay in my outstanding amount of which I did and I was told my line would be connected within three hours but it didn’t happen. I called again and a guy by the name Max told me he can see the payment was made but unfortunately it won’t be connected within three hours like I was told and apologised and told me he’d load a call and call me back the following day of which he didn’t do. I called again and a guy by the name Navesh if I’m not mistaken confirmed he’s seen the payment but unfortunately the call wasn’t logged so he’d log a call and so I waited after some hours I called again and a Schaba tells me I’m still owing on the line and even owing on a contract phone of which I don’t have a contract phone with Vodacom but I’m owing and they can’t connect my line until I pay the 900 and something for that phone. Worst service I have received they just send you from pillar to post.
