Trailblazer Service - refused

<p>I took my new Tailblazer in for a service at 10,000km because the change oil warning message was displayed.</p> <p>The staff at the Edenvale Branch were very professional and helpful, however the maintenance department declined that the oil be changed due to the fact that the vehicle had not reached the service interval of 15,000km.</p> <p>I reported that on the website and I received a call explaining the same thing, whereon I asked for a mail confirming their stance, which I am to yet to receive.</p> <p> I disagree that the oil shouldn't be changed, the vehicles system is set up to warn of the oil quality and I would like it on record so that if I have future problems with the engine I can refer back to this incident.<br /> </p> <p>Besides that Chevrolet website I gave posted a complaint on the GMSA website as well, with also no response </p> <p> </p>
