The missing question or piece of information is: when were they lost?

Recover until cancel is the step needed, followed by resetlogs - if your database was in a recoverable state to begin with.

Agreed, if they could just apply one redo log/archive log, they could do an open database resetlogs; Otherwise, they should take a good look at their backup and recovery procedures...
