So over at Samsung NZ's facebook page https://www.facebook.com/SamsungNZ they had a competition to win an S5 by guessing a phone number to dial. The first to call the number wins

There were clues given each day for the last few days
Here are the clues:






The answer to question 1 is 21 hours, The answer to question 2 is 4, the answer to question 3 is 2mp, and the answer to question 4 is obviously 5
By these I would assume the number would be something like 021 4 2 5

And now they say someone won it and that The correct number was 021 364165. How do you get that number from the clues you were given, WTF
