Went to my local store on Monday to purchase a Dyson V6 which was on offer for £199. This was not in stock so reserved it and given a reservation number and told to collect today (Thursday). Asked if I paid now or on collection, informed on collection. When I went into store today was informed the price was now £299. I explained I had my reservation number etc., but was turned away. At no time was I informed that the price could go up even if I reserved the item. Absolutely disgusted with the service I received.
