How to get a response from AMELI?

It's been nearly a year since I have applied for a social security number in France. I come from European union and the day I applied I was told I am getting a temporary number in 2 weeks and a permanent one within 3 months. It's been nearly a year and I don't have a temporary number nor a permanent one. All of the documents were sent correctly. Since October/November whenever I call them they just tell me "I am setting your case as urgent, await response". It's been 3/4 months of no response. Going directly to a local office I get told to call the support number. I have not been informed about any status change, any documents needed or anything.
