Erie Insurance Group

My son switched to Erie this past summer because I have had Erie for over 30 years for auto and home. This past month (Oct. 2023) he got an email which was forwarded to him through his agent 2 weeks old and stating his policy for the house would be cancelled in 3 weeks because of his roof. I asked my agent if he got a new roof would it resolve it. My agent said if I could get it done he would then ask his underwriter for approval. So I did. I even sent him a picture the day the roofers were doing the work because I was racing against the clock. The cancellation would have taken place midnight on a Tuesday. I sent the final completed pictures and didn't hear back so I called the office only to find out my agent only works 3 days a week. I had that office forward the pictures to the underwriter on a Friday. On Monday I contacted my agent and told him I can't wait for the underwriter to read his emails and please just call him. I didn't hear anything all week and called my agent one last time before the end of that week and he wasn't there. I advised my son to apply for new insurance the Friday before the Tuesday deadline of cancellation. So needless to say I cancelled my home and auto policy of over 30 years and my son and I went with another agency. My agent led me to believe the new roof would solve everything. My agent was loyal to us until he wasn't. Several people told us to sue. What would you have done?
