Nossan is the worse cat dealer ever

I am experiencing very poor service from Nissan. Took my vehicle In for inspection due to power failure. I was told it's a battery issue which was drained by an malfunctioning button in the ignition. They sorted the malfunction but they did not deal with the damage caused on the battery. Now my vehicle has been in Gateway Nissay since 26 June till now. It's taking them forever to sort the issue let alone that they want to pi the problem on me as they were not interested I wanting to find out what was draining the battery until I screamed at them. They dont bother giving feedback till you post on Facebook. They are even less interested as to the inconvenience caused as a result of the fault and what implications that has. Never dealt with such *********** people. They are the worst car dealer ever.
