Application done without consent and breach of information use

I am so disappointed by Vodacom sales people who just process an application without talking to me. I was notified by email that a new contract has been submitted for reference number *** and an application has been generated on my profile which I called the number specified 082 135 and Wandile Nxumalo assisted and advised that indeed an application was processed for a home internet connection. I am very much not safe with Vodacom my information is compromised and there is no respect for consent I need this fixed urgently.
