Supporters were attacked with metal chairs and battered by up to 100 hooligans who swarmed on the pub where they were gathered in the French city for the match in October.
The supporters were then sprayed with CS gas by police who they said ignored their pleas for help.
Eyewitnesses said the Blues fans were enjoying a peaceful afternoon and evening at the Australian bar when the unprovoked attack happened.
Goodison Park officials sent a letter to the French authorities highlighting their concerns about the treatment of Everton fans in November.
But they have still not heard anything from the Prefecture of Lille, two months on.
On the Everton FC website the club said they were “disappointed” at the lack of response.
The post continued: “The letter was penned by Goodison officials following lengthy consultation with fan groups in the wake of the Europa League encounter.”
The club also sent letters highlighting concerns to a selection of senior bodies in England, France and Switzerland.
Officials from UEFA’s security responded, confirming they will use the information provided by the Club ahead of preparations for Euro 2016 in France.
The FA’s security unit and the UK Football Policing Unit were also both keen to be made aware of any formal response from officials in Lille, with a view to planning for Euro 2016.
