Renault service disaster

Very poor service. I was told to bring in my car for service when it is on 15 000KM. Then recently it had a problem so I thought it's because it needs service I took it in, they fixed the problem then I asked about service. I was told they need approval from Capital Division. The consultant told to me come in Friday for service but I didn't go I called her to cancel and postone for Monday of which I brought in the car this morning. To cut the story short I was told that I need to pay for the service, even though I'm not supposed to be paying for it, they say its late of which the consultant that works for Renault told me my kilometres were too low when I called to make an appointment before my car finished a year. The service is very poor at Renault.
