Complaint Against a Service United Kingdom

Yanwen delivery service / Yanwen delivery service

I ordered an item from Facebook and received the item, but had been forced under my back gate.
When I opened the order it was so squashed and damaged. 
It had been smashed and is unusable. 
To say I’m disappointed is an understatement, I am very angry as I can’t afford to pay for something to not be able to use it.
I have attached the photos of how I received the package and will take this further if I don’t receive a satisfactory response.
