Renault Warranty claim at Lionel Motors Rustenburg

I took in my vehicle Renault Kwid on 10 September with a fault and a noise in my engine, they had a look but could not assist me for ALL the technicians were on training for the whole week. I booked my vehicle for 17 September 2019, on the same day they said they temporarily fixed my vehicle but it needs a ignition coil, my vehicle is still under warranty and it will be claimed through warranty. in a period of three weeks i did not receive any feedback from Lionel Motors, when I phone to follow up the warranty lady is never available, and i leave a message, no one ever gets back to me. The lady who booked in my vehicle only stated to me that the part has been ordered and that they will contact me soon to book my vehicle to be properly fixed. Up until today no one came back to me, no feedback, my vehicle is still not fixed... I phoned to speak to the branch manager but he was unavailable, so I spoke to the financial manager, she is now investigating just to assist me. This is very very poor service, I have been told by them that I may not drive long distances with my vehicle but for more than a month no one is getting back to me, not even to let me know if the warranty claim was approved or not. I'm still in the dark with no answers.
