Unfair assessment of the claim

i have been covered by outsurance since 2015 for my business which is a Day Spa and hair Salon in the cover its included cover for products for an amount of plus minus 160K Policy Number OT***8. due to worlds lockdown the shop was closed on the 27th of march 2020 and we were only allowed to open last week of June 2020 we then opened on the 1st of July 2020 on opening some of our products were spoiled due to that fact that were opened and no used for months. when i put a claim it was rejected ( claim No. ***5) and told they do not cover for contamination when i explain that the products could not be contaminated as there are not living my products were spoil because of the country's lockedown it was indicated that they do not cover for lockedown and referred me to the clause that speak of contamination and the policy never indicated Country locked down its only talk of war ********* acts
