I no longer have access to my Facebook email

You no longer allow us to sign with Facebook without stating any reason or giving us a heads up. And now my 17 years old IMDB account which I use everyday is suddenly evaporated.

The problem here that I no longer have access to the email I signed up to Facebook with (Hotmail) because it was so long ago, and Facebook gives you the option to change the email address, but the problem is that when I signed up on IMDB in 2005, it was done with this Hotmail address which I no longer have access to, and since you stopped dealing with Facebook here, I'm now stuck and can't get my account back.

I sent to your customers service team many emails and they always reply with an automated message without giving any thought to actually assist me. 

So, please assist me and all the people that face the same problem and give us a solution because this is not fair at all.
