Stimpack run out

Me and my brother bought the Mengsk bundle on the day he came out, a month ago. As we all know, there were issues that prevented you for gaining XP for the first 10 days, so Blizz said that they will be extending the duration of the included Stimpack Boost by 10 days, before any Stimpacks run out.

However, ours run out. Any ideas when this extension will be coming?
