Precise Auto Protection Won't Refund after Contract Cancellation Azusa California

I am the same position as has been describe in several previous Rip-Off Reports about Precise Auto Protection.  Precise won't refund the unused portion of my cancelled policy's premium.  Over two months ago I attempted to cancel the contract and requested a refund.  To date, Precise hasn't even extended me the courtesy of acknowledging reciept of my cancellation letter or responded to my voice mail messages.  Initially, I talked to customer service at their Administrative company, who then referred me to Customer Service at Precise.  I then talked to a gentlement at Precise who first tried to talk me out of cancelleting the policy but who finally provided me with a post office box (PO Box 305, Azusa, CA 91702) where I was to mail my letter of cancellation.  That was more than two months ago.  During the past several days, I have called Precise's customer service number several times, and either never had a person pick up or was transferred to a voice mail box where I left a request for status. I also tried going on line to their Administrative company's web-site (provided during the initial part of their Customer Serive Phone Menu's introductory words) to see if I could determine if my contract had been cancelled, but that web-site (WWW.INDF.COM doesn't appeaar to even exist - so even their Adminstrative compary seems to be part of their rip-off scheme.  I also tried the credit card disputed transaction route, but since that transaction occurred more than a year ago, I was out-of-luck there too.
