Angry, frustrated and dissapointed

I took my car in for repairs on the 15th July 2019, i have been waiting since for a part that they saying comes from France, i am struggling to understand why must i wait for 21 days for a part when things are made easy in this 21st century, which courier company do they even use which takes 21 days day to deliver.

I have been told there are no loan cars available, it's raining in CPT and it has been raining since the beggining of July, i am very angry and frustrated.

I do not even know why Renault is still tradin in SA if there are no spares for their cars in this country
