Apple India — Fraudulent selling of insurance

I purchased my apply xr in feb 2020 from sector 35 c chandigarh. They sold me the insurance by saying that it includes 2 times repair and 1 time replacement. I confirmed the later extra charges while taking the claim and the person denied any. Now when i made insurance claim, the insurance brand oneassist denied by saying that can’t be done. This is the trick between apply and oneassist and customer suffers. Its been more than 10 days, my phone is with them and no body is responding on my calls etc. I want to take this matter legally now
