India Post — courier not received and no one is working or responding on it.

Address:	Krishna, Andhra Pradesh
Website:	www.indiapost.gov.in

Consignment number: en[protected]in
Bag number: ebn[protected]

We submitted the courier in vijayawada on[protected] and they said it will be delivered to from address by the immediate next day because it is speed post and we paid 285 rupees.
I am waited for it even after 10 days still there is no proper update in the website, no customer care numbers are working. Then i decided to complain it through e-mail there is no proper e-mail id also, so then i added all the e-mail id's related in any which way to this service and posted he complaint and then i got the reply from karnataka stating that they will forward it to hyderabad.. Then we got the call from hyd stating that delivery have to deal with may orders so they are not able to call me then after discussion we asked to send back the courier to 'from address' then they promised that they will deliver with in 2 days, fine we waited for 2 days there is no update in website and in any way after that two days it is being 1 week now and still there is no update or response. Meanwhile i contacted through twitter, mails, facebook no one is replying.
Basically we are the students and we have to submit the assignments in he university and now it was blocked in the courier pack. Please understand and make it solve asap.
