I bought a Dyson dc-27 from Argos Bromley Mall on saturday 24th April 2010. The vac had no suction and we took iy back to the store and had it replaced on Thursday May 6th. Yes we went through all the checks with Dyson on telephone. The replacement vac seemed to have the same problem. It has less suction than the cheap hoover cyclone bought for 50 pounds. However, Dyson are unable to send their engineers on weekends. They do 1 in 4 saurdays so if you are a professional couple, the dyson 5 year guarantee means nothing. Today we took the vac back to Argos with the receipt exxactly 7 days after purchase, and the store manager at Bromley mall, refused to refund us even though we had the original receipt and replacement receipt. He asked us to get Dyson to sort this out. Dyson say they cannot refund us as we bought the product from Argos and not directly from them. However, Argos do not make it clear while advertising that if you buy a dyson product from them, your statutory rights are void. Even now they advertise the same product with no warning that you do not have your usual 30 day guarantee. This is absolutely disgraceful and I feel completely cheated. Do not buy any Dyson product from Argos - be warned.
