MRF Tyres — MRF Wanderer 215/60/R16 - tyre sidewall punctured

I bought a new Kia Sonet that came with MRF Wanderer on 1st of Sept. I went on my first outstation travel. While on the highway drive, I found the front left tire was losing air pressure. On inspection there was a puncture in the sidewall. Surprised that this issue happened within 1500 kms o[censored]sage. This is due to the poor quality of the tire. Came to mrf warranty centre and they refused to replace tire even at a concession price. Very bad experience on my car usage.
