I purchased a brand new 55 inch Dixon tv on the 25th of September. 10 days later the tv light does not work. When I went to the store they told me they could not replace it just yet and they would have to send it in and this process will take up to 21 days. The process is longer than what I had the tv for. My main problem is that I asked for some sort of confirmation that I had given the tv in. I get told "don't worry I have your number". I need some sort of confirmation that I have given my tv in which they say they do not do. I do not see why it is hard to make a copy of the page I signed at least to make both parties happy. Because come 21 days later I rock up with nothing and say I handed in a tv, what can I show them to state this.. Nothing. I spoke to a Kim who then said the documents would be printed later and she would send me the confirmation, I took down her number. When I left the store I messaged her a reminder and till now I have no reply. You have taken my money and the tv back and I have nothing to say on paper that they have acknowledged that its with them.
