Loss of consignment

I have been with them for three years now. I used to get a proper service until the 30th of August 2021. I sent 2 parcels to kempton Park, i got an sms saying my consignment is lost. When i claim tjey ask if i had taken insurance. I said no then they wanted slips of the items i sent or i cannot claim anything , luckily i buy things online so i had managed to get few of the tax invoices back dated to 2016 answell. After this whole tiring process, im told my items were not insured so i can only be refunded 1000 voucher to my tcg account... Like What da?. This is devastating shem.
