Respected In-charge
as i have sent a parcel which is 20.900kg in weight from tiruvannamalai(s.senthil kumar) to karaikal(mohamed kassim) on 19/10/2016 [booking no: [protected] ]
that parcel was delivered on 20/10/2016 but the parcel has opened and some items(nearly 8 kg) where missed and resealed during delivery . but unfortunately the delivery boy got signature with the parcel containing 20.900kg in run sheet.

then i have contacted the booking office they told to contact customer service and contacted to customer service they said that during delivery you have signed that parcel contains 20.900 kg, so u cant ask us like that.

so i am helpless kindly ensure that these things should not be happen again.

now my question against that courier company was :

1.is there is any weight conformation testing during delivery time ?

2.if the delivery boy is thief means who is the responsible?

now i am not complaining this to get my things, it is to stop such irresponsible company activities like this.
thanking you
yours truthfully
