Blue Dart Express — about courier service

Address:

Patna, Bihar, 800001

Dear sir,

Myself abhijeet kumar.
My debit card was coming through your courier service on 24th april
But it was said by your office that your address is not written correctly, whereas my address is everything written correctly and even before this stuff has come to my address. But i ignored this thing and i have done its compliant but it has been 2 days since then. So far i have not got my courier. What is the problem? I do not understand.
Even i also said that something which belongs to me, can get me from the office but he said that whatever the debit card comes from the bank, you can not get it at office.
I am going out of my address for a few days, tell me who will receive it.
I do not understand one thing why the couriers do not call phones.
I will not present on my address from tomorrow.
Now, tell me who will responsible for this.

Thanks
