why does Freemi Debt Counsellors have my personal details and why do they lie about me giving consent?

Received a call from number *** and the person introduced his company as National Credit Regulator. He called me by my surname and said they help reduce interest on accounts and he saw that I have many accounts. I asked him to list those accounts and he mentioned my bond account, car and credit card accounts with correct financial institutions, quoting my ID number correctly as well. I questioned him why he is calling me to reduce the interest rate instead of doing that with the financial institutions where he should be regulating as he says he is NCR. After back and forth, he hung up and in no time, I received a notification on my mobile phone, confirming that "I, with my full name and surname, my ID number , gave consent to Freemi Debt Counsellors on 2024-05-21 to request/obtain a Credit report on my behalf with the objective to perform an affordability assessment relating to my current Debt exposure". I was a confused because i did no such and also shocked by the new name now, Freemi Debt Counsellors as they were introduced as NCR, and with my personal details that were available to them.
