Renault review: 1st service 15000km not covered by renault as advertised

According to Renault when you buy a new Kwid model you get 2 services free, the 15k and 30k service, for some reason unexplained I had to pay self for the 1st service at Renault Centurion, the 2nd service however was done free by Renault Centurion leaving me confused, I asked them why I had to pay for the 1st service but not for the 2nd one and they had no explanation. No one at Renault has any explanation for this and has no resolution for this issue.
