[Removed for Content], Pretty sure that the box states Subscription needed. Yes, you will get 60 days free with the Complete Collection, but you need to prove that you can in fact pay a subscription (thank you spammers and plat sellers!).
You may be able to contact support directly and see what they can do for you. If you wanted to try the game free, perhaps you shoudl try the 14 day trial first? The complete collection works still to give the 60 days free after that, but instead of an extra 60 days you will be given the 60 days minus your trial period.
