Negligence of IDM insurance

Most probably the worst company i have had to deal with in terms of cancellation of my insurance. I paid everyone and settled my accounts received my clearance certificate on 30 January 2026. Up until now they have not updated and closed my insurance. On my credit report the idm insurance says i am in arrears, this obviously has an impact on my credit score. When you eventually get hold of them they state it has been cancelled and will mail a confirmation letter. Up until now three months later... no letter nor any changes on my credit report. I have never in my life been treated in this way and it borderlines total negligence on IDM groups side. PEOPLE I WOULD NOT RECOMMEND ANONE USING THE INSURANCE!!!!!
