Intergrity Cargo - damaged and shortfall of good transported

Goods received after 4 weeks were opened, damaged and sort. Delivery time should be 5 to 7 days only! Intergrity Cargo offered us a refund, credit or replacement of good. We choose a refund and now they are only willing to pay for the missing goods. They are not willing to compensate for the damaged goods. Intergrity Cargo also said it will be resolved the same day - a week later we are still waiting!
