Telkom is a total ******* ! !

In Oct 2020 i receieved a call from Tawonga Mapfumo from my net to promote a sim only contract @R199 with Telkom of which i accepted the offer.The driver delivered a router with the package which i did not say i want and returned the router back to telkom ,telkom then advised that a new sim card will be delivered to me which is a sim only contract and i should return the previous sim card and router, which I've returned. There were several up and downs as Telkom could not get the pick up address correct , but none the less ,I recieved an invoice that Telkom will be debitting me with R574 for both sim cards and routers which i dont even have.I tried calling the call centres and no one can assist me, ive been emailing Tawonga and her manager Deborah Kayembe and no one is getting back to me. For the month of Dec , i was debitted with an amount of R269 but my contract should only be R199..I am paying for services i dont even have ,lik wat the F ?
