Poor administration services

I wrote here over two months ago when this insurance company gave excuses and didn’t want to pay my claim for a washing machine. I have since cancelled this insurance and parted ways with them. Almost 3 months later they still haven’t closed their account on my credit profile. It’s over 60 days and I am not sure why they would rather not do what they need to do. This is impacting me negatively as it appears as though I hace a commitment with them which I don’t. Can this account be closed immediately? Thanks
