Terrible service at Lionel Motors Rustenburg

I have Renault Captur that experienced a technical failure on 14 Dec 2019 on route to Rustenburg. The car was checked in Lionel Motors on 17 Dec 2019. At first they promised to finish diagnosis and repair the same afternoon, however, it wasn't. The following day on 18 Dec 2019 I was told they have changed plugs and suspect dirty/ wrong petrol and they will drain and test. I had to extend my stay and incur more costs on accommodation with my family. Seeing that there's no progress, I ask the manager to arrange courtesy car because I had doctors doctor's appointment in Bloemfontein on 19 Dec 2019. Manager indicated that he doesn't have any though it is dealership responsibility at least for 5 days then Renault SA takes over. Up to today 24 Dec 2019 I have no idea what's happening to my car because I had to rent a vehicle to get back home.
