Vox once again billing me triple the amount I should be paying.

I so badly regret signing with this ISP that has trapped me with their contract and absolutely sh**ty service. From the time of installation till now, I have nothing but disgustingly poor service and treatment as a customer. The latest issue in a long line of issues, is being triple billed because VOX doesn't know what the hell they are doing and when they doing something. They suspended my fibre with no warning and expect me to pay R1770 somewhat for the fibre that they neglected to bill because they got confused with the LTE package I had. Cry me a river Vox, you guys are astoundingly useless and then expect the customer to suffer for your misdeeds. Vox said there was no services to bill against my account prior to Jan so I don't understand where they found services to bill. As far as I'm concerned Vox has breached this contract. I know my Consumer Protection rights. I can't be held liable for this bill when I have the text communications showing that Vox said themselves I have no active service from their side.
