Are you 100% sure ? Cause the rule says :
"- The winners of Pool A and Pool B will be drawn to play-off against the winners of Pool C and Pool D to determine which two nations will advance to the World Group II play-offs in April."
That draw already happened today. It's A vs. D and B vs. C.
Elsewhere in Europe/Africa Zone Group I, Great Britain were given a testing draw with hosts Hungary, Romania (arguably the dark horse of this year's event with two players in the Top 25) and Latvia.
The winner of that group will play the winner of a pool that will be contested by Ukraine, Austria, Slovenia and Israel.
