Hi Mate,
Firstly check here
https://eu.community.samsung.com/t5...rs-refund/td-p/358805/highlight/false/page/56
But really, as liek me, you purchased in RS you should have a much easier time of it.
I started it all off with a reasonably informal email where basically I said, Look, I purchased the KS7000 (8000 for you) for you from you and it was advertised at the time that it would work as a "smart things extender" which doesn't actually exist and Samsung have said it never will as they have stopped software support for this TV.
Obviously i'm very unhappy about this and the fact that no updates are coming after (insert number of months here) and as I understand I'm entitled to a full refund for miss-selling.
Provide this link as well:, its a archived version of the page at the time and I found the one for your screen:

With all that you wont have much trouble, although they might try some silly business at first with regards to offering a straight swap for a TV that's not as good.
If I was you I wouldn't accept a Q8F (the newer version of a KS8000, most people seem to say the Q series is a bit a downward step in terms of PQ)
