Lot of if's in there, but it's a free call and until you get a PNR they can't even keep score how many times they've told you to bugger off. Here in Los Angeles I'd eventually call one of the good folks on the AA rtw desk with the same request.
IBL immediately grabbed the space for me, btw. That may have been before the feeding frenzy on cheap ex-MRU began, though. (As ticketing is quite separate from reserving seats, I suppose you meant that you actually have the seats but are afraid the res will time out and you'll lose them. If that's not the case, BA/MRU is a sorry place to do business.)
You're so far ahead of me here, I'm not even sure I understand all your suggestions! But I really do appreciate your attempts to help a greenhorn.
The last time I booked (through the HRE office) the local office was adamant about not helping me at all. I guess I could keep trying various agents - it's a small office and I could end up putting the phone down a lot if the same person keeps answering.

Even if they did relent and book one (or more) leg(s) for me, how would they transfer the booking to MRU for issuing? (BTW it's not a free call in SA - not that I would mind paying for a call that solved my problems.)
I don't have the seats! I don't know how to do that without the help of BA, or a TA, in MRU. Am I missing something obvious here?
And I've given up on MRU-LHR as no A seats are available within ages of my required dates. I'm happy to to MRU-JNB-LHR instead. But even those are evaporating like the morning mist.
