I have sent my important medical claim document from surat on dated 08/12/2017 (Which i have to submit to the claim company urgently), to ahmadabad. On 10/12/2017 it was received by dtdc ahmadabad hub and that status was showing in website but after that till date 15/12/2017 status is the same. And i am taking follow up since last two days to customer care and person who is handling surat office, but from all the person i am getting different answer and actually the company didn't know where is my parcel as the parcel having much important document, so i haven't seen this type of bad service of any courier company. If my claim company refuse to accept document as it is not delivered in time than who will take responsibility.
