Warranty Claim rejection

Extremely poor insurance, I have a *****ulent claim take place on my warranty and I declined the use of it over a year ago, today I want to claim on my warranty and they declined it because apparently I claimed for it a year ago, I have a rejection letter from last year where I told them not to accept the claim because I was not the one making it today they refuse to help me, no repairs were done on my car but they insisted they want an invoice from the year before even though I explained I never made a claim horrible horrible service
