Until 2011 I'd spent about £6k with them and they had been fine. Then the issues started. Bought an item which was one of these 'if you buy this, you get this for half price' kind of offers - I only wanted the half price item.
Emailed me confirming shipment. When it arrived the second item wasnt there. Emailed - nothing. Twitter - nothing. So I phoned their premium number to be told it was discontinued. What was worse was they they didnt refund it. Told me I'd have to wait 10 days. I waited - no refund. Emailed - no reply, etc. At this point I was annoyed, so asked to return the entire order for a full refund as I'd not opened the other part of the product. They refused it despite me being within the 30 day window.
I asked to speak to a manager who I was told would phone me, and obviously that never happened. A month later and I got trading standards involved who were about as useful as a chocolate teapot. I never did get a refund for either item (yup, that includes the item they never sent) and the gits closed my account for 'abusing the ticket system'. I had 2 tickets in there, of which I'd made 4 repies to as they had never replied to me.
Simple customer courtesy.
Prior to this cockup there was the £1 sale which they screwed people over with (and got in trouble with trading standards for) and then there's the reviews which on numberous occasions they've been in trouble for faking.
As I recall they were/are also suspected of posting their own deals on here and other deal submission sites, but obviously that cant be proven.
When they worked they were great. Problem is they are absolutely crap at customer support, and have shown they don't give a damn about the customer.
Dont forget the photo that came out at christmas too - they had a photo of the office all decorated for xmas and it was pulled very quickly once they realised you could see a piece of paper on the pinboard saying 'Number of refused refunds this month' like it was some sort of challenge.
They've been in trouble for all sorts of stuff. The Reg is a good place to take a looksee:
