i rent 3 large storage units at a storage sight. i have no insurance on my contents in the units. the sprinkler system went off during christmas holiday and we were contacted the next day when they opened. ther was about 6 inches of water on floor and the unit that was under the one unit that had the sprinkler is drenched. the manager offered a new unt and a free month. my stuff is ruined. the contract states they are not liable. is there anything legally i can do?
