Don't let it lie Pete write to the Chief executive of Currys and fully explain including this " Id rather not go to trading standards about this but unless I get some satisfaction I will have no option" Also quote your local Newspaper for that area - That usually get you a reply!
Also quote the exact act of law and the appropriate section - That makes them sit up
and at the Bottom of the letter write this " This letter is written without prejudice and may be founded upon in a court of law" Their legal team will buzz!
Plus State in your letter the date you want a reply and if they don't then actually report them- For them not to reply within a reasonable timescale does not go down well with TS.
