Damaged furniture

Bought kitchen unit online, was delivered on the 18/11/2025@19:10. Was about to assemble it 10 minutes after delivery, then i saw dents/scratches and broken glass. Then i stopped and srartrd taking it pictures and video. Forwarded to customer service same night. Their reply yesterday was i boxed the item then claimed it had faults, their last email was their team delivered the item in good condition because I signed a delivery form. My question is what will I achieve to damage an item i order with my hard earned money in 10minute?
