try this [not tested]
select
     msisdn,
     max(max_topupvalue) max_topupvalue,
     max(max_topupvalue) max_topupvalue,
     max(min_topupvalue) min_topupvalue,
     max(min_topupdate) min_topupdate
from
     select
          msisdn,
          maxtv max_topupvalue,
          case when topupvalue=maxtv then topupdate else null end max_topupdate,
          mintv min_topupvalue,
          case when topupvalue=mintv then topupdate else null end min_topupdate
     from
          select
               msisdn,
               topupvalue,
               max(topupvalue) over (partition by msisdn) maxtv,
               topupdate,
               min(topupvalue) over (partition by msisdn) mintv
          from
               temptable
group by msisdn
