Hartford did every dirty trick in the book

PLEASE, PLEASE HELP. I had Hartford GLTD insurance through my employer in 2004. They did pretty much every dirty trick in the book including, as I’m almost 100% sure of, document forgery. After finally recieving my file that I requested from them, wich took months to recieve & numerous hippa violations, a supposed lost mailing to my PO BOX never recieved, despite numerous inquiries, they emphatically stated package delivered to PO BOX had verified same nearly 2 weeks later when the latent lies became more than I could tolerate, continuous checking with my post office, they suggested I get the tracking # & check it myself, to confirm what sender has been stating. Upon doing this & Hartford reconfirming delivery approx. 2 weeks prior of package to PO BOX, gave me an invalid # for a postal service delivery. This went on for another 2-3 days, when they finally called back leaving me a message that they made an error & package was shipped by UPS to PO BOX & diverted to the front stoop of my home address. When asked how this could occur, they stated UPS doesn’t deliver to PO BOXES. Now 3 or more weeks later, files containing all my personal information & medical records are MIA – honestly I doubted highly that they ever actually sent them untill I verified with UPS, supposedly dropped on front stoop nearly 3 weeks prior. SCARY. They called MDs without an updated autorization, while denying me, BLATENTLY did something to have DRs who had treated me for years prior & had submitted that I was permanently totally disabled, now sent them a DOL work ability form from a providor specialist I SAW one time & utilized this to coerce my prior practitioner to totally contradict his prior 3.5+ years of ability & disability. Now stated able to work @ median level, with no restrictions. I am an RN & have now not been gainfully employed since my MVA in May 2004. Sooo much more to tell, I have taken too much of your time… Thank you. Respectfully yours, Lisa.
