Unauthorized Credit Check

On Monday 20/10/25 in the morning I received a phone call. The person started talking about that I pay to much interest. Because I do not have any debt, I said that it is not a convenient time for me to talk, which was the truth. Later that day, I received an SMS stating that I gave CDS Consulting permission to do a Credit check on my name which is false. I am very worried what they plan to do with that. I was hoping that you can advise me on what to do. I see there is other complaints similar to mine. Phone calls, then unauthorized Credit Checks.
