I believe my storage unit was rushed in to auction too early without proper notification. What type of lawyer can evaluate my case?

Storage unit had a running balance for October and was billed the middle of this month for November rent. Rent is due on the 1st. In the past, I typically always pay middle to the end of the month. Example, I paid September's rent on October 1st. I was attempting to pay October's rent on October 31st, when I was told the unit had been sold the prior day at auction. No certified letters were received, no emails received, but phone calls were placed. They only called in attempts to collect the debt, and to inform me about the auction process, never to say 'pay us by this day or your unit will go in to auction'. When I've paid the rent late (such as the example given above) they had told me it's not their policy to auction off a unit after a month...that as long as they hear from someone they won't do it. Payment history for the unit is consistent, so this decision is not consistent with past behavior.
