Narrative:
We encountered some wake turbulence behind an airbus; that we reported and then requested and received a vector to vacate. In the process of approach (behind that aircraft) we were broken off the 28L visual and given the 28R ILS; which we accepted (greatly increasing our workload - specifically on the account of our discussing the wake turbulence aircraft immediately in front of us and our avoidance techniques thereof). We checked in with what we thought was the tower; and at this very busy airport on this very busy day; and during the landing roll out did a radio check after re-entering the tower frequency and were told to contact ground; which we did; and taxied to the ramp normally. Upon landing neither crew member was able to positively recall acknowledging the landing clearance.
