Narrative:
Three approaches into sfo. First; we briefed at altitude my ILS 28R; but a report of 1/4 mile; we changed on descent to captain's cat ii and re-briefed; then ATC during delaying vectors gave a change around 6;000 ft. South bay to ILS 28L and re-briefed and bugged again; then vectored behind B777 heavy and getting bumped around. The plane stayed level at FAF!!! It is not clear all of what happened there; but the GS got full scale before we started down; so we went missed; admitted it to ATC and now they played the major role; both times they re-vectored us; for ILS 28L and then 28R finally; they left us high; very high; and the whole reason for this as soon as possible is that under the challenge of three attempts; I thought for sure we were cleared the approach and started down but had to clarify again that we were cleared because of the unusual height.unfortunately; they didn't give us the ILS clearance or the appropriate altitudes earlier; but we kept making requests for lower.
