Vodacom *****ulent applications by door to door salesman

On 20 May 2023 a Vodacom door to door salesman asked me if I would be interested in the latest promotion of cheaper Vodacom Fibre. I informed him that I am happy with my current service provider and not interested. he asked if someone from Vodacom can contact me and explain. I agreed and he asked for my cell number and name. I am a current Vodacom customer with my cellphone contract. On 21 May I received an e-mail from Vodacom that my application for Fibre line has been approved - note I DID NOT do an application. I contact Vodacom on 22 May and told them that the salesman committed ***** and they must please cancel this order. Vodacom telephonically and via e-mail confirmed that it has been cancelled. Today; 23 May I received an SMS from Vodacom to inform that my order is on its way via RAM couriers....what order? What are you sending me?? I also notice the invoice added to my cellphone interim bill. I sent another e-mail today to inform that this is ***** and needs to be cancelled. My reference number for the cancellation is SR***
