I am not happy with a Dyson fan I purchased at JL. When trying to return it at the store, my return was not authorised. I believe that this product was mis sold to me. I inspected it before purchase, it was deliberately made to feel very efficient working together with five other fans and under air conditioning at the store. I felt it was very powerful. The store was also very noisy and I was under the impression that the fan was very quiet. However, when I opened it at my home conditions, I realised that this fan was not powerful enough and it was also very noisy. It was my great disappointment to hear that because I have opened the fan and although it was in it's original packaging and have not been used, just tested, I was not allowed to return it. I was also misinformed by the wrong information on the purchase receipt that I could return this item within 35 days. This is very wrong. Any other store would have authorised my return. I am very unhappy and feel that my customer rights have been breached.
