Oh how sweet doesth tasteth revenge
Having worked very briefly for DSG in the distant(ish) past I can tell you what a horrible company they were and probably still are to work for.
DSG makes more money selling spare remote controls, hoover bags and extended warranties than anything else. I remember when they introduced the store line number where you could ring up and speak to someone in a call centre instead of speaking directly to your local store.
They used to treat their call centre and retail staff like shite and the store line was just a way of getting rid of people from Freeserve tech support, putting them on lower payscales and employing loads of students from Sheffield part time on crap pay.
Heaven forbid if you wanted to take something back to a local store if you'd bought it online - no store would take ownership of the issue.
DSG deserve all they get for treating their staff terribly over the years. Their staff, though, deserve better opportunities with better organisations.
