TDR — tdr rejected by very technical answer.

We booked ticket with pnr [protected] dt 3/8/2019. It was booked upto chennai, but we want to visit tirupati so upto renigunta. Darshan tickets are also planned accordingly.
Train started late by 7 hrs. Though it was late that late was in our scheduled programe limits we sat. But at karjat it was diverted via panvel due to heavy rains & landslide in ghat region. No railway authority was in position to ntell us timings as well route of train. So we left the train. Authorities told us that situation is wellknown to everybody you will get tdr refund. From karjat we went somhow toour residance at dadar at 5 am in morning.
Now by giving technical reason that tdr was not filed within 4 hours is can not be possible.
Pl. Look into the matter & arrange for tdr refund.
Thanks & regards
