Customer care-Terrible service!

Good day

My 2021 Renault Kwid Climber AMT has been making a loud humming/whining sound on 1st & reverse gear since I pruchsed it brand new. I complained to the dealership , and they said it was normal and nothing could be fixed. I was not happy so I called RENAULT S.A They advised me to take the car back to the delaer, I then booked the car in, the dealer opened a CIR to report that the sound is normal, and will not cause further damage to my car long term.

Since December 2022 I have not receievd this letter, to give me piece of mind. I called and emailed 2 agents from Renault S.A customer care department 'Mbulelo Ngobese' & 'Sifiso Kubheka' who promised to email me with the letter, but did not. I tried calling them , no answer. I am disappointed and frustrated with this poor level of service received.

Please contact me to sort this out, or I will take this matter further. If my car breaks, I will not be held liable for repair costs arising from this sound.
