I have made a payment to the below company (www.protair.com) to send me the attached goods - I have paid them however the goods they have sent me are incorrect - they have sent me goods to the value of 50USD whilst I have ordered to the value of 900USD - please advise what action I can take against them - I have tried to email and phone them but to no response!

I am very angry and would like a full investigation by your police.
