I can’t help but think that if the OP had flown with QR just a few weeks earlier then you would have had the same complaint. The Al Safwa F lounge in Doha has been opening “soon” for eons. Yes it’s open now, but QR haven’t had an F lounge since Hamad opened. In my experience the ME3 have their own unique ways of going about things and that usually involves poor communication and seemingly never ending delays. If that doesn’t suit, then vote with your feet and fly someone else.
