This got resolved today. I sent a PM to Red Roo on Monday night and yesterday got a reply to say that it was being forwarded to the Frequent Flyer team and that they would be in touch shortly. It was also a nice touch to find that Red Roo (at least one of them) has a name!.
Today I got a call from Andrew at the Frequent Flyer centre to say that the QF website was at times showing incorrect points and SC's that could be earned in the summary before a booking takes place and as such were happy to honour what I thought I would have earned for those flights that I took. I was credited the extra SC's and points not long after the phone call.
Towards the end he also mentioned that if I got near to my anniversary and it looked like I mightn't get enough SC's to re-qualify for WP this year to give them a call and they would be happy to talk about comping me to WP again for another year based on my history.
Well done QF, Red Roo and Andrew...happy camper here.
