bughunta is right. No need to take it anywhere near them if its working to your satisfaction.
Although PCWorld has gone up steadily in my estimation in recent years, their staff turnover is very high and the level of knowledge is poor.
Mostly they know tiddley-squat except what they can read on the side of boxes.
I wanted to open a Business Account with them, but after sitting alone for an hour in the almost deserted Business Area listening to an "agent" explaining the intricacies of the floppy disk to a customer I thought better of it.
