Simon you are not alone! We sell pig arks and they are our major competitor. I get lots of calls from people that have had the same experience as you from them. It is a fact of life that you can’t always deliver promises due to varying circumstances but they seem to let a lot of people down and don’t even stay in contact to let them know what is happening. All I can say is go to trading standards because someone needs to do something about them. You are covered buy the distance selling act so there should be no problem getting your money back. Let me know if we can help!
