Rachel, I simply can't believe that any firm can seriously expect to get away with this claptrap in this day and age ! 
Their "damage limitation" clauses that say 28 days, or anything else DO NOT LIMIT YOUR LEGAL RIGHTS - which in fact have no set limit, apart from "reasonable".
But one thing you can be absolutely sure of - it isn't less than 12 months !
They are in fact lying to you about your legal rights, simple as that. Which is, of course, illegal.
And do they really say 72 hours on TV 's ? Well, it's rubbish, and a lie. Take a recorder in with you and tell them you will be recording their fantasies !
They either have no idea of the law - or know it, and simply don't like complying with it. A solicitor's letter is the perfect answer, but why should you have go through all this when the law is on your side, and they are behaving illegally. Simply, you can take them to the Small Claims Court.
Citizen's Advice ? If you still have one ?
Seriously, print off the "A-Z" version of the Sale of Goods act and give it to them. THEY have to sort it out - they should send it to Sony on their own behalf because they are responsible, not Sony.
And I'm afraid Sony may very well charge you for simply looking at it (£28 last time I heard] .
But it isn't their fault this firm is refusing to abide by the law.
I really am staggered........... Oh, and if you do leave it with them, take good photo's of it from all angles, make a note of the number, and get a signed official reciept saying it is in their care. But I'd say you were seeing a solicitor........
