Once again disappointed in Renault:-(

I heard an unfami**** sound om my vehicle (Renault Kwid 2019 Model) on Sunday (28/11/2021). The following day(Monday 29/11/2021)i contacted Renault Tygervalley to advise them and they said the car needs to be collected by their Roadside assistance and booked in for inspection, which happened.The Tuesday (30/11/2021) i received an email to say the vehicle is sorted and ready for collection. I sent my sister to collect the car as i was working and was unable to collect myself.The evening, to my disappointed surprise , the vehicle had the exzact same sound i initially sent it in for. Now you must know, i live im Mitchells Plain, i work in Blackheath, me carting this vehicle up and down to Tygervalley is no joke on the tank(whereby petrol is already a nightmare), can anyone please HELP me as this is not my first disappointing encounter i have with Renault :-(
