I'll just go via my credit card company if PCW are funny.
Under the Sale of Goods Act 1979 goods must be as described, of satisfactory quality and fit for purpose.
The Sale of Goods Act makes reference to ‘the seller’, this is the shop, the retailer, or the individual you bought it from, and is who you made the contract with. It is not the manufacturer, and don’t let the shop tell you otherwise! If there is an obvious fault with the item at any time within the first 6 months and it has not been caused by wear and tear or misuse , your first port of call must be the shop you bought it from. They have the responsibility to put the matter right, and should not evade this responsibility by referring you to the manufacturer in the context of a guarantee or warranty. Even after this 6 month period, if the item breaks down prematurely , you should always go back to the shop or retailer in the first instance.
When you buy something from a shop you are entering into a legally binding contract. Therefore they don’t have to give you a refund simply because you have changed your mind. Only if one of your statutory rights is breached (i.e. that the item is damaged, of poor quality or not fit for purpose) do they have to give you your money back.
The Sale of Goods Act requires that goods be accurately described, of satisfactory quality and fit for any purpose specified. In other words, they must ‘conform to the contract of sale’. If this is not the case within the first 6 months after purchase, you have a range of remedies available to you which you should take up with the seller
If your goods fail to meet any of the above criteria then you could have a claim under the Sale of Goods Act.
