Poor Technical Backup Samsung TV's

<p>Having just bought a 40" Samsung FHD TV I wanted two questions answered namely, 1. How do I use the 4 suppledplastic mounting fixtures to fix the TV to the wall. (no info in the manual) 2. Can the Antenna input socket take an adaptor so that a Y-video cable can be used in this signal input. </p> <p>Firstly I tried their online support, without any success other than fobbing me off to the store where I bought it from, I then tried their phone support who also could not help and advise I send an email to :- ********** Needless to say I have not received a reply, despite sending a follow up message.</p> <p>Pretty shoddy treatment and lack of service, from the top selling TV brand.</p> <p> </p>
