Connect Auto Insurance by American Family American Family Connect Proverty and Casualty Insurance Company Changed my rates and automatic debit unilaterally De Pere WI

While I was on summer vacation, Connect insurance added 3 people to my insurance policy, and claimed they send a mail notice by regular mail which I did not receive.  When I returned, I phoned Connect to see when my payment would be deducted and discovered that the amount was 2.5 times the agreed amount and that 3 persons had been added to my policy.  I had to pay a $30 stop payment.  Connect refused to correct this change to my policy and has sent me to collections.  They have since agreed to remove 2 of the people retroactively but are asking for personal information on the third which I do not have access to.  None of these people reside with me.  I cancelled my auto insurance with connect. Connect seems to be threatening me in order to data farm on others.  They could have excluded these persons without raising my premiums.
