Pathetic service delivery at Renault

I had taken my vehicle in for replacement of a timing chain in December 2019, this had been done and then I collected my vehicle in January, upon collecting my vehicle I noticed a scratch on the front bumper which I don't recall being there, I then called the advisor and explained what happened, I had been told repeatedly that the person that checked the car on the arrival was not there and the day I took my car in there was no vehicle inspection done as per records, I have tried calling this branch several times and have sent e mails to this service advisor, I am still awaiting a response. Renault after service care is pathetic when compared to other companies like VW. It's very disappointing, I am now sitting with a scratch on my vehicle and no accountability from Renault whatsoever, utterly sad.
