Milex review: Portable air conditioner

I have bought the air conditioner for the hot days. The product works and is not damaged, but I have used the product whole day in my apartment with an unsuccessful outcome.

The apartment was still hot and did not cool the area. I had called the store to return the product and had been told that I bought thr product while on a promotion and do not qualify to return. I had not been told about the promo non return and I have tried doing my own research and I could not find any policy that says this.
