Keep calling....keep calling...explain what happened...how you fixed it..and give them the name of the officer who said they were too busy...talk to the watch commander ...everybody you can....sometimes they really are too busy...like very serious crimes..and sometimes they don’t want to be bothered. The person who said they were too busy may a serial service denier or just having a bad day...good luck...
