Aviva Auto Insurance Reviews

I am a female 61 years old never had an accident in my life haven’t had a ticket in more than 25 years. Two years ago on an icy rainy night, I literally hit a wall my car just slid! No damage to the wall no other cars involved but 10 thousand dollars to my car... I had accident forgiveness so one year after the accident my insurance went up Approximately 300 dollars? Year 2 after the accident my insurance has gone up an additional 600 dollars so in 2 years $9 hundred dollars? Where is the accident forgiveness? This is totally unacceptable and my agent keeps saying “well you had an accident” yes BUT I had accident forgiveness so how does that work? I work from home therefore it’s pleasure driving only. I park it in a garage it has onstar onboard snow tires in the winter BUT years of being a loyal customer I dinged $600 this 2020 renewal?
