I have PC World's Head Office phone number at last, It was given to me to contact them if I had any problems picking up my laptop replacement from the local store and if I had any problems with the refund for the laptop I sent back. I really would have liked the number over a month ago when I was getting nowhere with PC World customer services, I was repeatedly told that even they didn't know the number, that they could only email to head office themselves. After countless phone calls emails etc... they finally rang me, and in 10 mins everything was sorted. If I could have spoken to head office directly over a month ago things would have been so much easier. Here it is 01727 202120 I hope this helps people to sort out their problems too.
