There are not any conditions which forbid withdrawal of July.
When I made a cashout in 25th/July, I knew Poker770 had warned about withdrawal between 1st to 30th June. They obviously mentioned about that at the 5th paragraph(below) of their T&C.
And I re-checked T&C in case they had changed the conditions. As you can see in linked page, there were no changes, zero words about cashout in July.
If a player makes a withdrawal between 1st and 30th June 2012, he won't be eligible for the Magic Box promotion for his deposits made from the 1st to the 30th June 2012.
And now, they refused to pay in baseless argument.
Sienna: Hello, I'm Sienna from Customer Service Poker770!
Sienna: How may I help you?
zukotto1919: Hello Sienna, Could you tell when the Majic Box $10 would be issued?
I'm not in hurry, but just want to know.
Sienna: You have received the first 2 stages?
zukotto1919: June and July, I received
Sienna: The 3rd stage has been already credited
Sienna: But as you registered a withdrawal in 2012-07-25
Sienna: You did not qualify for the stage in August
zukotto1919: ah..show me T&C please?
Sienna: I suggest you contact the PokerStrategy support in this matter
Sienna: They will be able to offer you further details
Sienna: As this promotion is issued under their terms
zukotto1919: I read T&C at the first time , but didn't noticed such conditions. You don't have T&C now?
Sienna: I am afraid not
Sienna: As I said this is a PokerStartegy promotion
Sienna: They will be able to offer you details
zukotto1919: k, I will have a contact with them.
Sienna: I can only confirm what I have already brought to your attention
Sienna: the reason you did not receive the 3rd stage
Sienna: is that you registered that withdrawal
Sienna: Thank you for your cooperation
