Good morning. My name is Marc. I'm a licensed attorney and I will be happy to answer your questions. I can imagine how vexing this is for you! And I cannot imagine why the company is so unresponsive. I'm afraid I cannot offer much more than you may already know. There is only so much you can do to give them fair notice of your claim and a reasonable opportunity to resolve it. After that, the only way to compel the company to respond is by filing a summons and complaint. I'm not sure how much your repairs are. The amount at stake will determine whether you can file in small claims court, which would be less costly and time consuming for you.
Upon filing suit, the company will no longer be able to ignore you. Well, they could ignore you, but then you would be granted a judgment of default against them. The company could answer your complaint by denying your claims of liability and damages. But, if the CFO is at least a little rational (not to mention, just doing her job), she will either contact you to negotiate in good faith or she will notify the company's insurance carrier. If the latter, you might expect a call from their insurance adjuster, who will likely be eager to settle for any reasonable amount that you can support with proof (receipts, estimates, photos, etc.).
It's good that you called the police. It doesn't guarantee that the company will outright lie by denying any responsibility, but it makes it less likely and it adds credibility to your claim.
Two recommendations: (1) document everything - repairs, estimates, and keep a log of phone calls - date/time, who you spoke to, what was said, what followed. And (2) before filing suit, make at least one formal, written demand by sending a letter, certified mail stating you claim, attaching any proof, and closing with a statement such as: "Please consider this my good faith attempt to resolve this matter without resorting to legal action." If the CFO has any sense of duty at all, she will at a minimum forward your letter to the insurance carrier.
I wish you a speedy ans satisfactory resolution to this frustrating matter! And I hope I've provided you with useful information that helps you better understand your issues and options. If so, please feel free to rate my answer, since that is the only way I can receive credit. Or let me know if you have any further questions.
