Just adding another update to this.
I commented on this thread about a month ago, and since then two more people have replied saying they are also having exactly the same problem with the GOTY DLC not being available.
I'm still waiting for an update from the EA representative who dealt with this issue previously.
At this point it seems pretty clear that this is still an ongoing problem affecting multiple GOTY owners, rather than an isolated account issue.
Has there been any progress or investigation into this, or is there simply no one looking at it anymore?
It's been a very long time for a problem involving DLC that people have actually paid for.
