No parts at Renault

I bought a Renault Kadjar in December 2017. I met with an accident in October 2018. After the assessment of damage it was found that the radiator was damaged. I now have to wait 21 working days for the part to come from France(according to the consultant at Renault). After I contacted the consultant, she had already told my husband she will be rude to me. Aside from the attitude from Renault, is Renault saying that there are more than a 1000 Kadjars in South Africa but there is not a single radiator available locally? Are we living in the 1990's where parts take months arrive? On top of this the consultant from Renault said that stock was depleted. Does Renault not have a proper stock tracking system ? I will never buy a Renault again and if anyone asks me about Renault I will tell them exactly this. I did tell Renault I am putting this on Hello Peter and they could be bothered!
