Unauthorised credit enquiries by Vodacom

I app**** for a contract with Vodacom back in February 2020, I was declined. They called me at the beginning of May offering me a new contract. I was nolonger interested, I didn't accept it. What worries me is that they made 2 credit inquiries on my name. I did not authorise those enquiries. I did not want any service from them, I did not accept their offer. I need those two enquiries removed.
