The exact same happened to me! First when a reminder was sent at the beginning of July, I received the "your file is currently in queue for review by an officer” answer, and then after the 30 days, when we called again and the officer said he couldn't send another reminder, I emailed the CPC Ottawa address and got the answer that says "your file is currently under review and requires additional verifications". As far as I've been told whenever I called, we are not in SS and there's no RR either... Honestly, I think they just try not to send the exact same answer when we ask again, but I don't know for sure why this happens.
