Vodacom customer care agents

In 2023 I submitted an application for a cellphone contract with Vodacom which was decline. The year is 2025 and I have Vodacom customer care agents calling me to inform me that my application is successful, how? I keep getting emails that my application is successful and according to my knowledge I did not apply for a new contract. Why do they still have my information? And why do they keep calling me? Manoko from Vodacom customer care centre was rude and hung up in my ear when I was question why they still have my information and submitting that I have app**** for a contract.
