Unauthorized Credit Report Access

I received a call from a call centre agent of this company by the name of Amanda advising they received information that I’m being overcharged on my accounts and loans so they want to help me to cut those down. When I asked what accounts and loans she said they don’t know as they did not receive that particular information. When I said I do not have any accounts and loans she said okay thank you and proceeded to drop the call. Immediately after that I received an sms stating that I authorized a credit report to be drawn in my name and the reason is affordability assessment. We did not have that conversation about my credit report being pulled and I did not authorize this. Why was this authorized when I did not authorize such? I emailed the company to query this and followed up again but received no feedback. Pulling my credit report without my consent is absolutely disrespectful, interfering with my credit score for nothing by pulling this report. What a very unprofessional way to conduct business.
