Just feels very very wrong - claim fraud

1) I was hit by a car on my rear bumper. I exchanged insurance info with the one (Person A) who caused the accident. ( I had Farmers and A had Safeco)
2) After a few days, I was contacted by a Farmers agent "B", and she told me that "A" filed a claim on me. "B" told me that she confirmed "A"'s information with Safeco. I explained the cause of accident and "B" also agreed that it was 100% "A"s fault.
3) I was contacted by my local agent "C" saying that Safeco would cover only $300 among $1300 of the estimate. My deductible was $1000.
4) I called Farmers agent "B" and said that I would contact Safeco myself because I didn't do anything wrong.
5) I called Safeco, and "A" was not in their system. She had fake insurance and suddenly a different Farmers claim agent started to contact me.
6) I received $1300 from Farmers since "A" was an uninsured motorist.

There is something terribly wrong with what happened to me, but I am not sure where to report this to. No one seems to be interested in fraud by insurance companies.

I do not know whether it is related, but after a year, suddenly my premium was increased from $260 to $400.

Can you give me some advice on this? I try to forget it, but it just feels very very wrong...
