I made a purchase a few days ago. I too called to change the delivery address and have been unable to get through for two solid days now.
Ironically, the day before I made the purchase I called to make an enquiry and got through first time! Having read the reviews on here since then it does seem like it is indeed a scam.
The 'happy' reviews (and even the reviews which are designed to look bad but in fact are good because people 'actually got their items') are obviously all made up. If only I had seen this before I made a purchase.
This won't be the end of the matter by any means but I could do without the ball ache to be honest - I'm fighting to save my job. I mean you just don't need this nonsense do you?
