Have been trying for over ** hours to arrange return for TV that is too big, with the intention of purchasing a more suitable model, thereby requiring a lesser refund. *After ringing a number that was given incorrectly, a Return Form was completed and submitted TWICE. I awaited confirmation of my selected collection date. *As no response was received, I was kept on hold, on a different number, for a total of over FOUR HOURS. All calls resulted in my being disconnected, after listening to a message saying that 'colleagues' were aware of my calls.*You had my money immediately yet evade it's even partial return.*Whilst you claim to have a LiveChat, no details are supplied.*You make it inordinately difficult to contact you by multiple means, and have no callback facility.*HOW AM I EXPECTED TO RESOLVE THE SITUATION????
