Good morning everyone,
Just thought I'd post an update. I contacted the FF and QC service centre this morning asking about this. The outcome of the call was slightly ambiguous. The lady on the other end said it definitely looks like I have retained Gold (being the 600SCs), BUT nothing could be done immediately until my case is run by the seniors upstairs. In the girl's defence, she was apologetic and said it seems most likely Gold will be reinstated.
So I will let you all know how things go in the next day or two. Hopefully this debate of 600 vs. 700 SC retention for PG will be solved once and for all.
(And I know this issue seems petty, especially to many of you who fly a lot more than this, so I apologise for the pettiness - but thank you for all of your opinions, advice and tips)
