Are you in the UK?
With mine, on the Samsung website it showed preparing for despatch when I already had notifications from DPD, the delivery company, saying it was on its way...
£50 voucher isn't bad for a day's delay
Ordered mine on 5th. had confirmation it would arive on 8th. Still pending on 8th but assured by samsung shop it would be with me so i stayed in all day (took a day off work). Didnt arrive so called again. They said Monday for sure. Another day taken off and wasted. no phone and useless support. Now im gwgetti told i wont get it until 15th! Total joke.
