India Post — item delivery confirmed - haven't received mail

Address:

Guru Nanak Ave / Majitha Road, Amritsar, Punjab, 143001

I ordered an item off of a website, and have been getting the run around from india post - they've shipped it to the wrong location multiple times to areas with zip/pin codes that are not in the same area. They've even suggested i pickup the mail myself, which is not the service that was paid for. As of today the item shows it's been delivered, but i've received no package, received no phone calls or communication, and none of my neighbors report receiving either.
