Manufacturer Plate

I bought a Kia four years ago. Everything was alright until this year. The Tunisian technical agency for land transport firmly required a new manufacturer plate from Korea. I went to your agency in Tunisia of course , and i paid a new one. Meanwhile the technical agency for land transport took my car's registration certificate and gave me a temporary paper to replace it (just for three months) until I get my new manufacturer plate. This was four months ago. Now Kia agency said they are still waiting the plate from Korea and the technical agency for land transport refuse to provide me with any papers to be able to use my car!!!What to do??? Please help!!!
