Received damaged goods and Kalahari just dont care

I purchased a truck for my 4 year old son for his birthday next week. Yesterday this was delivered I immediately opened the parcel and to my surprise i get a completely damaged and dirty truck, the box was not even sealed, I am 100% sure this is a truck that was returned previously as anyone can see that's a second hand truck, firstly its a white truck that is dirty, the one mirror is broken off, one wheel is missing the body of the truck is bent, the one back door is off. How on earth do you send something like that to your client. I phoned Kalahari numerous times yesterday as I explained to them that it is my sons birthday next week and I spent all the money on this huge truck, I need this replaced urgently or a refund and I get told that the courier people will only collect the item in 2 or 3 working days and after the item is assessed it will take 14 days for the refund to be done, they just don't care if I don't have any other money to buy my son a gift, a manager phoned me late the afternoon to say that they will speed up the courier services to assist and yet almost another day has passed and no-one from Kalahari or the courier service phoned me, this is unacceptable service
