I don't think their customer service team has a clue whats going on, they just tell you whatever they think will get you off the phone. I phoned them the other day to ask why mine hadn't arrived yet when others who ordered later had received theirs and I was told exclusive colours take 4 weeks to become available. I was then called a liar when I pointed out that people had received exclusive coloured handsets, including the graphite that I ordered, already.
I did bag myself a £100 voucher for asking to speak to a manager as a result of the liar comment but no progress with my order. I just checked their store and they're advertising all the colours as in stock which set off alarm bells however when I tried putting through a test order, when I get to the shipping stage it's giving an earliest delivery date of the 3rd March for the graphite.
