Premium increased by 98%

I have a problem with budget insurance, I had an accident in February this year where I wasn't at fault, someone bumped me even the accident report prove that. Then after the claim, they have increased my monthly premium to the figure where is equal to double of what I was paying, yes I did expect an increase after the claim but not double of what I was paying. I used to pay less than R1800 Then now new monthly premium is R3400 which is too much for me to afford. I tried several times to ask them to review their decision to meet my affordability but they refused. I am writing this to request them to consider my request that reverse their decision to punish me. It's not fair they come up with a unaffordable premium, it seems like they are chasing me away because I can't afford R3400 per month, it's too much. For the fact that I was paying R1800 then it becomes almost double is not fair. Budget insurance please rework my monthly premium, it's too much.
