Mechanical claim

I have been with AA mechanical warranties from 2020 . I recently logged a claim for worn parts , and they requested for pictures of damaged parts , diagnosis report and *service record* . I did provide them with everything and the service record of 2022 and 2023 , I couldn't provide them with 2020 and 2021 because of lockdown Pandemic . Meaning the car wasn't in use as often due to regulations we were living under 😡. Now the insurance don't wanna approve my claim and it already took longer than I anticipated, 3 weeks without a vehicle ......... I'm really beginning to doubts this insurance as my service provider.😕
