Speed Post — speed post customer support number not reachable since 2 days

Address:

Pune, Maharashtra

I have an an important document couriered to me by speed post, i am trying to track the status in website, it keeps jumbling between pune nsh and mumbai nsh offices. So i went to post office and they informed they will receive it today, but again in website it showed it went to mumbai nsh and never went to nearby post office of my area.
I am trying to call customer support number which is not reachable from 2 days, this is very pathetic. We have no idea if website status is correct and we cannot even speak to customer support and ask the status as numbers are never reachable. Why do they have customer support numbers then?
