Pure nonsense

Good day! Yesterday I recieved a call from one of your agents citing that I was short listed for a competition that I had entered with woolworths he then asked me to confirmy ID number. From then on, he started asking me about how much I'm earning and spoke about credit vetting and all. He then hung up when I tried to get more clarity on what he was on about. What nonsense is this? I have asked my bank to freeze all my accounts because of you, suspecting that you are **********. I have been trying to call you on 011 523 300 and 011 523 334 with no success.
