The Sales of Goods Act 1979
This is an Act that manages the sale of goods that are bought and sold in UK, and the permanent contract between both groups. The contract of sale states that the transfer of goods from a seller to a buyer is completed through a money agreement - this is the price.
Goods must determine a level of satisfactory quality for the price that the consumer/customer is willing to pay. And meeting the description and relevant details at time of the purchase. These details might include the level of expectation that an item may generate, e.g, second hand goods will provide much less expectation than a brand new product which will have a much higher expectation of the quality of the goods and will cause concern about expectation if it has a fault.
Goods should be suitable for purpose, i.e - they are able to carry out the purpose for what they were designed and created to do. A seller should reveal the purpose of their goods and they have a responsibility to make sure that they achieve that purpose.
The Sale of Goods Act amendment in March 2012 states that if the product is faulty within the first 6 months of purchase, the consumer is entitled to assume that it was sold to them with the fault present. This means that the goods were not of a reasonable and acceptable standard at the time of purchase and the seller is in breach of their statutory and contractual commitments, according to the Act protecting customers through their statutory consumer rights.
Back to the original Act of 1979, these consumer rights covers anyone who buys faulty goods becomes entitled to a free refund, replacement or repair service, and the responsibility falls on the retailer to provide this.

Companies are not allowed to use misleading or underhand tactics to get you to part with your cash. Misleading actions include advertising goods that don't exist.
Sales tactics can greatly influence a consumer's decision. Traders who fail to take no for an answer, refuse to leave until a contract is signed or use threatening behaviour will be committing an offence.
A practice is considered aggressive if the average consumer’s freedom of choice or conduct is significantly impaired.
