I bought a portable air conditioner 12000 BTU to use in the living. Despite the fact that the label stated 12000 BTU is idea for 500 sq2.ft room , it takes forever for the room to get cool during peak hours. It liked I didn’t use an air conditioner at all, so I went to Rona to ask to exchange for higher BTU air conditioner in hope the new one would work more better. The customer service staff told me air conditioners are finally sale, and can’t be exchanged or refunded. I felt shocked. I was not informed about it upon my purchase. Or else I would never have bought it. I’ve been shopping at many warehouses and had never encountered any like this. It likes they don’t care what you’ve got. You pay the money and that’s final. It’s very unprofessional and unsupportive. I have no confidence to suggest anyone to shop here, me myself it would be the last time I shopped there.
