Extra Space Storage Ripped off by Extra Space Sorage - I lost all of my belongings. Rocky Hill Nationwide

On March 20 I called the Rocky Hill location where all of my belongings were being stored since July of last year. The purpose of the call was to update my contact and billing information.
The updated information was received by the manager of the location at the time. After noticing there had been no charges to my credit card on my May or June statement I called to inquire.
The manager saw in the notes that the information was provided to be updated but was not.  Because they had not updated my phone number they did not reach me. This resulted in a two month balance.   The company vacated my unit by auctioning off all of my belongings. 
Originally the company had acknowledged this tragedy was a result of an error by their employee and assured me they would rectify this. Now management has explained that the company’s legal department believes that legally they are not responsible to compensate me. They do not feel obligated to provide me the funds necessary to replace my belongings. 
In summary Extra Space failed to update my information, sold all of my belongings, acknowledged they made a big mistake, and then decided legally they were not required to compensate me for the loss of all of my possessions. They failed to charge the card I provided and when I became 2 months late sold $20,000 worth of my possessions to cover $300 they were owed. I can't believe they won't make good on thier mistake but more alarming is that they are allowed to and actually benefit from not updating someone's account and selling all of thier belongings.
