Vodacom wrongdoings

On the 28th February 2025 i received a call from Vodacom online telling me i qualify for cellphone contract,i told the him/her to call back later as i need to speak to my husband,when the called back later that same day,i told them im not interested and ended the call.Today the 30th March i went to try and open a cellphone contract at Game stores,only to get told i have a contract in progress from Vodacom,i was in shock,i never gave anyone permission to process the contract,i never give permission to anyone,So if i never go an apply for a contract phone from Game i wouldnt have known that there is contract in process from Vodacom that is ******* because i gave no consent. Im so angry because now im wait to for something that i want because a person did the wrong thing.What do i do now really now
