Inaccurate credit listing for month to month car insurance cover!

Momentum insure has updated my personal credit report on a car insurance cover that belonged to business. The cover has been cancelled and the credit report still reflects as in arrears. I fail to understand why business insurance affects my personal credit score and furthermore the cover was a month to month cover so when you have not paid then cover is not provided, so why should it affect my personal credit score, please fix this error and update the policy to closed instead of arrears. Policy number is MT***1. By the way your customer service is one of the poorest in the country, i have tried to change banking details on the account but i could not get through to your customer service agents hence non payment on policy.
