Worst Service ever

I took my Clio VI Blaze in for service and when I went to fetch it I drove out and later realized they didn't reset the service light and other error messages. I took it back the next day for that sole purpose and I was completely ignored. When the guy who's in charge of that department finally came to me he spoke about something completely different. Then he said to me I should come back after 2pm he will do it for me. Like I don't have work to do during the day. I told him I'll come back the next day and when I got there I sat for more than an hour and even left without being attended to. I called the Renault customer care line and spoke to a lady there who promised to look into the matter and get back to me. To this day I'm still waiting. There is more to this and how I was treated.
