Vasanth & Co — Installation issue

Address: 1/9 Chettishwaran koil Street, Vikravandi, Vilupuram .605652

I have broughted new bluestar split AC on 7/4/21 at vasanth &co in vilupuram. I was called and asked to showroom person when is my installation. They simply said "we will check and update you".I was waiting for last 2 days No one contact me and not come for installation. When the time of purchase they said within one day we will provide the installation but still no one come and no one cantact me. Really I disappointed and unsatisfied your customers services. I will wait for today also if no one come or contact me. Surely I will return the product to your showroom on Monday and buy the new Ac from other showrooms . Please tell the what procedure to return the product.
