DTDC Courier & Cargo — extremely important document missing

Docket no-m62671789

I have couriered an envelop on 26th february from mumbai to kolkata. The same has been received on 3rd march. The envelop has been found packed suspiciously different than packed originally which indicates the envelop has been opened somewhere in transit and again packed. When the receiver opened the envelop after receiving, it has been found that some documents are missing.

Its completely disgusting matter.

Please inquire the above said matter and take action on dtdc so that i can get back my documents on urgent basis or dtdc should provide me a compensation of rs. 6000.
