Vodacom to block ********** application that was made through my name without my knowledge

Vodacom is a ****.. On the 29th of November 2021 I've received an email saying my vetting application is in process, I have not made any application with vodacom recently, my wifi account has been settled 2 years ago.. I went to the branch to assist me with this email, they could not get any information on where the application was made, how come all my details are correct including my ID number but they can't trace who did the application, when they check its 2 Hisense phones that were made by my name. The application also has my banking details of which they are going to deduct on the 27th, can vodacom help me because at the branch they couldn't get hold of the cancelation department that deals with contracts to block this application
