Thousands of pounds worth of goods left in the rain

Yodel left two large very heavy boxes on my drive in the pouring rain, damaging £1,000 of goods (I have the receipt to prove it!). They wrote on the card, parcels left behind wheelie bin. Phoned to complain to be told driver has indicated the parcels have been signed for! I said this is not true, response was well that’s what the driver had said! I explained the driver had lied and all I got was a ‘feedback’ will be given! Whatabout my damaged goods, whatabout the lying driver?
