I did write to CX already (to Peter Buecking, as Merry suggested), a couple of days ago...but I'm yet to receive a reply...basically I just told them what I posted here earlier...that it took them a relatively long period of time to process and approve my application, and then said flights within the period won't count, kind of unreasonable, and was always told to wait for phone calls that I never got, etc...and, at the same time, did tell them that my experience with them so far has been pretty good, enjoy talking with their customer service reps, who're always very sincere and polite...
I didn't really tell them something like you have to give me Gold or I'll leave, or something like that...I just describe my experience and see how they'll respond...I don't want to tell them what they should do, but rather want to see what they think they should do...
