Qatar Airways Privilege Club - Seat Selection

I can't seem to access my booking on their website?

Anyone know which A330-200 configiration is being used for LHR-DOH on
25th June and 5th July? I'm flying economy.

I called the reservation line and they said I'm on a plane with 8 first class seats. When I had a look on their website, the only planes with that configration are A340?

I just flew in today from LHR on a 330-200. And yes there seems to be only 8 seats in First only. QR has a few 330-200s with that configuration.

I've flown the A330-200 in first class, though on that aircraft there were 12 seats in first class (1-2-1). As you say, the A340 has only eight seats.
