If you chose not to continue to deal with an insurance adjuster on your own and not get a lawyer, you have a couple of resources to resort to:
(1) Call their manager directly. Don’t just say you will call them or threaten with this, because words will NOT help you much. Speak with action. Call the manager and ask him/her to call you back on their office’s expense. Discussing the situation with the manager will upset your adjuster, which will probably NOT help much, but let’s face – they will continue to treat you in this way, so at least for now you will have the upper hand.
(2) Described your situation in a brief 1-2 page complaint and submit to your State Insurance Commissioner’s Office. While they cannot pressure your insurance for a settlement, they are obligated by law to register your complaint, contact you back and force the manager of your insurance’s local office to contact you and discuss your case. Again, this may not help you much, but it does help public records. If every mistreated customer files a complaint, the insurance will eventually have to deal with the State Insurance Commissioner on a higher level.
