Pathetic Customer Service !

Over a year ago i bought my second brand new Renault and because of the problems with my left leg i bought an automatic , first I had a Triber and now a Keiger both (automatic ) . I am still regretting . They cannot get the gears to change smoothly and everytime they insist that the way the car is , surely you cannot be selling so many cars performing like that . with the keiger I have been back at least 10 times but when i asked for the records the cleverly have not recorded the come backs . They only have 4 on record . That is the back ground the last time 4th June 2024 they supposed to have sorted it out but the same week the problem comes back . So after i get my car back the next day a consultant phones me to rate their service ? I waste 15 mins of my life explaining the whole story and she tells me that Renault SA and the dealer principle will call me !! I am still waiting for the call !!! . Another Issue i had from the day I received the car there was a squeaky sound at the left back corner , everytime I took it in and complained they said that they would sort it out but never did , I suggested they check the shock absorber but not once did they show me that they took it to be tested ..... every time it is we have sorted it out . brand new cars and still pathetic service ?
