I was "caught out" with this very scenario mentioned in the opening post.
I bought a JVC set from Comet last year - a 24" LCD for the bedroom. I bought JVC because I assumed it still to be a reliable brand (in my household, in the eighties, JVC was generally quite highly regarded).
After 5 months of ownership the set refused to turn on. I contacted Comet who proceeded to mess me about something chronic. I waited weeks and weeks and weeks for engineers to show (then didn't), I then wait for ages for "parts" which firstly had to come from "JVC in Japan" - then were "in stock" at Comet warehouse - then the next day they'd vanished - then back in stock - then they told me they'd never ordered in the first place........anyhow, you get my drift......round and round and round in circles with Comet who were the most utterly incompetent and clueless organisation I have EVER had to deal with.
I did something on the phone with them that I have NEVER EVER in my entire 42 years done with a company - and that is, I shouted and physically screamed and swore at them! I am NOT proud of this - far from it - don't suppose I will ever loose my rag like that again - but - they pushed me too hard and wore my patience down to nothing with their contstant lies and incompetency.
Anyhow, I got Small Claims Court papers ready and they backed down at the last minute - literally - and offered me a replacement set to the same value as the faulty JVC.
I chose a Samsung in the end which was much better quality.
Needless to say, I will never EVER shop in Comet ever again.
I've dealt with some pretty useless and pathetic excuses for companies in the past, but Comet sure does take the crown in my book......
