Hello,I live in Los Angeles county,in the city of Azusa. The city sewer backed up and flooded my home. The city initially admitted that it was their fault,but now blame my neighbor's tree roots for causing the problem. They told me they would not pay my claim for damages,and that I should sue my neighbor! I pay for sewer maintenance every month on my utiliy bill,but it seems the city was not doing the sewer maintenance as they said they were. I have contacted my insurance company,and they said they would not pay because it was the city's fault. HELP!!,I'm caught in the middle!!
