Bad Customer Service

I wish I could have selected a zero for Renault Centurion's service. My vehicle, that I bought from them, went for service on the 4th of January 2020. After different reports from the booking agent and the workshop manager, I tried to phone the dealer principal on the 10th of January, with zero luck. I then mailed him. Received a phone call from him after my mail and he assured me that I was treated badly, but promise to pull the job card and phone me back. Needless to say, today, being the 15th of January, zero reply from him. So, in my opinion, they deserve a zero rating.
