India Post — courier never delivered

Address: 395009

I tried so many times to contact india post courier service but to no avail. They don't want to deliver my courier nor they want to respond me and give me any reason for it. Worst service ever, my courier is stuck in ahmedabad for forever and till date no response from them.

If anyone from customer service is reading this kindly let me know where is my courier and if you don't want to deliver it why the hell you are running this service.
