Unauthorised Credit Check

<div>I received a spam call from Finance Debt Solution stating that I was being over charged on interest on all my debt. I'm very well aware of the interest I pay, and I wasn’t interested in what he had to offer me. They gave me the first 10 digits of my ID number and asked that I provide the last 3 digits. I told them, I did not want to confirm my ID telephonically. Following this, the consultant said he was pulling my accounts on his system and that I would receive an SMS. I hung up on him as he was getting aggressive with my asking him questions around how he got access to my details. I did receive the SMS which states that I gave consent for Finance Debt Solutions permission to run a credit check on my name/ID number. At no point did I agree to them running a credit check on my name, surely this is not right.</div>
