Waiting.......
I would first start with finding the contact info for your state's insurance regulatory agency.... call them and ask them what (if any) is the time frame in which your ins. co. must provide a determination... and also mention what happened in your situation. to be honest, the state doesn't really much care how NICE your ins. co. is to you, so I wouldn't bother mentioning anything regarding that... but the state DOES care that your ins. co. follows the rules that the state mandates. There may be some contact between the state agency and your ins. co if the state feels your complaint warrants being looked into.
even if they don't conduct a formal investigation, if your ins. co knows that you've made a call to the state, at least they'll know you're not messing around. The fact is, you DO have control over the situation.... at least, more than you THINK you have.
good luck
