Worst Experience at Renault

I would like to express my utter disappointment for the worst service I am currently receiving from Motus Renault Menlyn. I took my vehicle to be fixed on 10 August 2023. Then, the service consultant (Dinah) called me on Friday, 11 August 2023, to tell me that they were taking the vehicle to a third-party company for diagnostics and the process would take at least 48 hours. Eleven days later, without any correspondence or communication from the dealership, I decided to go in person, only to be slapped with a R30 000+ quotation. I called the new service manager about their lack of communication and the exorbitant quotation, and he agreed to assist me. Today, 1 September 2023, I called again to check whether the vehicle was ready, and I was told that it was not and they had not even ordered the parts. 23 days later, and I was still told to wait for my vehicle. While writing this review, I received an email with a new quotation of R41 951. It has just gone from bad to worse. I have been using public transport to travel to work in Johannesburg from Pretoria East. The dealership seems not to care about us. If there is anyone that can help, please share the advice. It feels like a nightmare. I have been servicing at Renault Menlyn for over 12 years, and I am loyal to the dealership and the brand, but after this experience, I will not be going back. My advice to everyone out there: here's a testimonial for future reference.
