India Post — speed post article not delivered

Address:

Mahadevapura S.O. Bengaluru, 560048

Respected sir/madam
I sent speed post article (Tracking id-eg[protected]in) to mahadevapura s. O. Bengaluru. When i check the tracking status it shows "item returned refused" addresse was not even contacted by postman how can he put refused remark.

I made complaint on india post website with no.[protected] requesting authorities to deliver the article or return to sender address as soon as possible because it has some important documents in it. When i track complaint status it shows the message "unable to get complaint details please try after sometime!!" everytime.
Kindly resolve the issue.

Regards
