That's exactly what happened to me, I didn't click submit at any stage nor did I receive an automated response by email to say that I had applied, but as I said I received the auto generated email saying I didn't meet the requirements.
Anyway, I shall do as others have said and try a new email address and I too will try and do it all in one sitting this time.
I wonder if recalling one's application would resolve the problem, would prefer my normal email address rather than having to regularly check a secondary address.
