Sent a letter saying they were going to cancel our policy 6 weeks after we closed on our first house, and paid for a year in advance. Tried to contact someone to figure out what the problem was and all I got were automated messages trying to sell me more coverage and voicemails that were never returned. I really wanted to keep using them for insurance, but I cant even get them to call me back. My wife is stressed, I am frustrated if 0 starts were an option that is how I would rank them.
