Fray Bentos

I put the cheese and onion pie in the oven at the proper temperature and as after 10minutes me and my friend could smell burning, we both went to see what was going on and seen smoke in the hall!! When we took the pie out the oven the pie was on fire!!!! We had 2 young children of 3 and 4 in the house as well and were terrified something was going to happen and were in tears. We will not purchase another item as we are scared what might happen and what could have happened if we had left it 5 or 10minutes longer!! I have a couple photos but it isn't letting me upload them as it is asking for a link for them..
