Complete Collector's Edition Upgrade with full Complete Collector's Edition possible?

Damn, i wish i had seen this thread before i bought the complete collectors edition thinking i could add it to my existing account. Hope i can get a refund!

Got it refunded, for anyone who has done the same mistake.

Yeondan, I submitted a ticket and I received today the answer: we can't upgrade our existing account taking advantage from the 60% discount. This is the answer I received:

It's so strange and disappointing that that's the case. It doesn't seem sensible to me, because you could, for example, buy the complete standard edition for PS4, then buy the complete collector's edition for PC. So why shouldn't you be able to apply a complete collector's edition code on top of a complete standard edition code for the same platform, with just a warning that you already have the complete standard edition license?

That's good. I wish they'd be clearer with the restrictions in the product listing though. It says:

Includes a 30-day free play period. This can only be applied once to each platform on a single service account. This 30-day free play period is not applicable to platforms on which a licence has already been registered. User Registration and Service subscription required to play the Game.

"This can only be applied once" sounds like it applies specifically to the complete collector's edition. Especially since the next sentence implies that it can be used on a platform that you've already bought the standard edition for, but you don't get the 30 day sub time.
