Renault review: kadjar service

Good morning.
My name is Panos Bairaktaris and I work for a company name Agrohoum S. A.
The company bought a Kadjar 1.6 4x4 diesel at 12/2016 for my use as a benefit because I m the sales manager. The car number is ITO 8243. I pay for this car 200 euros per month taxes.
The car had a damage at September and I went to the company I had bought it which is Sfakianakis group of companies. They said me that the problem is that a pipe witch is for the clutch broke because from the beginning it was touch some gears and because the car is still at guarantee the will have the needed spear parts and I will have the car at 15 days.
Today the car is still waiting for the spear part. it now exactly 2 months after and nobody knows why the parts had not coming yet and also if they come and when. I already pay 400 euros at taxes for something I had not have and also I don't know when I will have it. The customer services of Sfakianakis says that the part exists at you but it not load at the track. That is what the importer says to Sfakianakis. Someone must lies. The importer, Sfakianakis or Renault. I feel very angry for my choice to buy a Renault car and if a don't have a very quick solution I will publice all this situation to every one a can.
I don't know what's happen but be sure the name of your company suffers with these situations and behaviors.
Waiting for and some explanation ASAP.

Thanks in advance
Panos Bairaktaris
