Right guys i bought my Samsung Q8 from them last year in december and they have both been brilliant. Now i wanted to updrade so sold one of my Q8's and ordered the new Q9FN which i rang the shop paid over the phone but had to collect it from the warehouse. Anyway after doing this i set it up at home and notice during football it had DSE and banding to which i was not happy with. So i rang the shop and the guy was saying id have to have a samung engineer out to confirm it was faulty before they would swap it out so i moaned and said it wasnt acceptable and he said send in pictures so i emailed them pictures showing the DSE and also a video of it. He then said he had arranged an exchange to which id have to drop the old one off at the warehouse and collect thr new one (bearing in mind this takes 2hrs 20mins there and back) to which i did. Now upon setting this up i didnt purposely look for any DSE and just got on with it until whilst gaming noticed it in the sky on BF1 whist panning so went and looked and noticed it again. At this point i emailed C&M and said that this seems to be an inherant flaw with the Q9 i was not happy with it and provided another video for evidence. The salesman rang me up today and informed me they have recieved the old set and they cant see any problems with it and that id have to have a samung engineer out to see if my newest one is faulty before they accept it back. This is all within 10 days from initial order to now. I said i wasnt prepered to have samsung come out on a brand new TV that i wasnt happy with the DSE/banding and he said there is nothing he can do as he doesnt class the TV as faulty. Now i am waiting on a phone call from the shop manager on monday and wondering where i stand and what i should say ? HELP PLEASE !!
