The advice you got is in fact correct.
I don't think you're understanding this correctly. The website states you may request another GUP on accruing 50k+ miles in the next calendar year (see below). This is a very different issue to accumulating 100 or 150 etc in the SAME calendar year and receiving extra GUPs. Contacting your local/BKK office is a good idea, however.
Gee thanks hgp, I should pass onto you the name of the boss of ROP, maybe you you should be so kind as to pass on your decision

. JohnSIN is a very busy FF in the Asian pacific area and you may have missed it but we were chatting about the arbitrary decision of the Singapore office not to renew his Gold status. He travels twice as many miles as I do and has been a tremendous supporter of TG. So can we have your input on this please.
