Thank you for advice

Hi Can someone please help me? I have home appliance cover with a large company and when I called them out to look at my American fridge freezer, they informed me that they could not repair it but offered me 30% of its value against a replacement. I found a product which was the same size as mine and the product replacement asked me to pay the balance which I did (on my debit card). They said they would order the product for me and that I would receive delivery details from the "supplier". Delivery was due last Wednesday so I had to take unpaid time off work. Delivery men arrived (3rd party national home delivery company) and my new fridge freezer was tail-lifted down off the vehicle. To cut a long story short(ish), one of the delivery men was used to these types of delivery and one wasn't. They unpacked my new fridge/freezer in the road and then attempted to carry it to my house. They dropped it more than twice. They damaged my laminate flooring and internal architrave. One man badly cut his hand in the process and the blood splattered through my hall and on walls. The fridge freezer was damaged (incl dents on front door). I have video/audio footage of the event. As soon as they left, I called the home appliance company which I have a contract with to inform them of the above. They said they would inform the "supplier" and that I would hear back from them within an hour. I didn't. I telephoned again on Friday and was told the same thing and I still haven't heard from the "supplier". Can someone please tell me where I stand? What should I do? Which of the 3 companies 'in the chain' is responsible for the damage to my house and new appliance? I can ill-afford to take more unpaid time from work - can I add this to a claim? Thank you for reading.
