honestly, i think it's a little fishy. as bad as that sounds. i mean, everyone who has called knows that getting an answer, let alone, a straight answer is hard enough but be given the "exact" date on which your case is going to be reviewed sounds a little too good to be true.
every time i have called, whether for DACA or for my I-130, i've always been told to wait 15 days or 30 days or 45 days but have never been given an exact date. if that were the case, i would LOVE to be told when a visa number will be available for me so i can adjust my status. LMAO
