Charged R1784.90 to refusal of service and unopened router

Considered taking fibre had an issue with a previous owner registration at my address. Vox calls me for application, I send my documents, I wait for weeks, I make a plan and take up a LTE contract. A lady calls from VOX to continue with the Fibre Application, I tell her to leave it I no longer need it, she sends a router via courier - I refuse to take it but courier persists and tells me to arrange with VOX to take it back. the package went back unopened and they send me a R1784.90 bill for cancellation of a service that I clearly stated over the phone that I don't want. Where shall I get the money?

watch out for these ****mers.
