CPI insurance. Got screwed

This might be a long one and please, for my sake, spare me the disappointed.

I got a car with no credit when I was 18 at a buy here, pay here place. (Mistake #1) I had zero knowledge regarding anything financial or how any of it worked. Long story short, I got preyed on. At the time of purchase, they told me they had to add CPI onto the loan to cover their asses, essentially. I thought, “oh that checks out considering in their eyes, I’m an unreliable 18 year old. Of course they’d be cautious” and took their word for it. (Mistake #2). They told me this would be a cheaper(!!!) option of insurance and I’d be good to go. So I thought, man what a deal! (Mistake #3). I happily signed my life away and walked off the lot with a piece of shit. (Mistake #143). Obviously nothing excuses my ignorance, but I was in a shit place and getting any sort of transportation actually saved my life.

1.5 years and abt 8 grand later, I get hit. (Minimal damage) Come to find out, my insurance doesn’t cover those damages. (NO WAYYYY. I’m using humor to cope because I’m going insane right now).

I assumed the CPI would cover shit because they told me it would. I’ve had full coverage for about 6 months now and read something about getting a refund for the time I was covered privately. So I looked into my loan more and realized just how much they fucked me over now that Ive gained more knowledge over time. I saw they could do a refund and remove the insurance if I had proof of insurance and a deductible at $500 or less. I looked at my insurance and realized my deductible was $1k.

I should mention I called them a few months ago and they said there’s no way they could remove it even if I had proof because it had to be removed within the first 3 months. Nowhere in the loan documents does it say that. Just says I need proof full coverage with 500 ded. BASICALLY I am just wondering if even a partial refund and removal is in the cards because I have done a lot of research and I’d rather get any sort of clarity before taking action.

Ps.

I am in the process of working with a trusted family member/advisor to get tf out of this and do something more responsible for myself financially. But a refund would help tremendously. Thanks for your time. :,)
