I can give wrong banking details for my insurance

We bought a new company vehicle and asked the new rep to get the insurance sorted. As the vehicle is company owned, the debit order will be for the company's account. The one mistake we made is that King Price loaded the policy in the drivers name (new rep) and not the owners of the company. He is no longer employed by us, and we would like to cancel the policy. After numerous contact and discussion with King Price,no such luck. . We are not the policy holder but we pay the premium. King Price will not even accept a letter from our bank confirming that the rep has no link to the bank account. King price's policy and procedure does not allow for this. They say I could be some mad man trying to cause issues. Can you believe this!!!<br> We need to get hold of the rep, which we can't, to phone King Price and confirm this. Not even King Price , with their policy and procedures, can get hold of him. They don't even have an alternative number. What to do??? Cracy!!!
