Made a mistake of buying a window equipment air conditioner from someone who lied to me

I went to meet up with the person who posted the window a/c equipment for sale and they said it works perfectly

I live up north and the summers are pretty mild, but occasionally you just need a little air conditioner to help you fall asleep at night. I just moved into a small loft and it does not have central air conditioner. It does have a wall gas furnace for the wintertime, then so far I have been keeping the windows open, the blinds down and fans on this summer time to keep myself cool. During the day isn’t so poor because I toil Monday-Friday in an office and our office has central air conditioner. I particularly suffer at night. I cannot sleep unless I am comfortable and under the blankets, and lately, I’ve been so warm and uncomfortable that I haven’t even been able to put the blankets on me so I haven’t slept well at all. I decided to look online for a window equipment a/c. I am on a particularly narrow budget and I figured a window equipment a/c would be perfect for me because I don’t need central air conditioner and I particularly only need it to cool our home office at night. I started searching for inextravagant window equipment a/cs and I found someone who posted an advertisement saying that they were selling a window equipment a/c for a particularly low price of $25. Something in the back of our mind told me not to do this because it didn’t seem right, but in our state of lack of sleep I decided to reach out to this person. I went to meet up with the person who posted the window a/c equipment for sale and they said it works perfectly. I got loft and installed the window a/c equipment into the window in our room. It didn’t toil and was noisy.
