I just bought him a beautiful air conditioner the day before yesterday. The installer never came to install it. I want to return it. How can I return it? Should I give him air conditioning?

I really don't know why I have to wait until it is too hot to buy an air conditioner. At this time, the installation and maintenance workers in the shopping mall are the busiest. Two days ago, my friend said that there were eleven people in their unit, and the installation workers were resting at home before and after. Even if it is returned, it is the same to buy another one. There won't be any workers waiting to install it for you. I advise you to wait, and at the same time call to urge you.
