mesh fence


Mesh Fence order is out of control

Occasionally,I contact one Australia client,he asked quotation and some details.When boss and colleague went to Australia mesh fence trade show,we invited him there.This chance helped us a lot,and confirmed the sample size.However,no any information got after that.One Skype information came in last Dec,quotation offered again.they would like to place order.Worked stopped cause of China New year,and I send -email to them when I was back to work.Quotation and negotation continues.I hope we can get  this mesh fence order,so best price offered.They thought our price is high,further discount is possible.We disagreed,then everything is gone.They placed order to another factory.
What should I do now???/
