In my experience as a Gold, if you call the Gold line and ask politely, they will give you the MCS-to-F upgrade price even if you have not been upgraded from MC to MCS.
I would also call the Gold line rather than the regular reservations line to see if you checked the box and make sure you are put on the list in the first place.
