It will not effect your personal credit at all. Even if you owe money and don't pay, the policy was under a LLC thus making the LLC liable for the balance if any. I have never seen ins business insurnce policy that has a PG attached to it.

Just call them up and cancel it and they may owe you money. Usually you put money down so a lot of times you will be owed a refund if you don't have the policy for the full term.
