44% raise in auto insurance premiums for one accident in 19 years with Allstate Insurance company?

I hit a parked vehicle and filed a claim to have my car repaired ($2800 in damages). The owner of the parked vehicle did not file a claim for any damage, even though they were contacted.
Has anyone else had better treatment from other reliable insurance companies and should I look for a change? I thought my loyalty meant something!
I am the only person on this policy and the only driver of my vehicle.

When you’re involved in an at-fault accident you automatically become a risk. The fact that you’re with a preferred carrier, they will raise your rate considerably for the accident was your fault. Loyalty is irrevelant with any insurance company. If you receive an infraction, you will get rated accordingly. Sorry, but it’s the truth.

I would definetely shop around for a better deal. I gurantee you will find a better deal.
