Vasanth & Co — Am complaining about delay installing air conditioners

I purchased ac in your showroom karur at 10th may 2020. At that time i asked him when will u install ac. They told 11th may definitely we will install. But till now they won't come and install. If i make call means they tell wait will come will come. It's not a correct response. Am ready to surrender that product. I don't want. If installing is a problem then who knows future service.
