Delhivery / Ssn Logistics — non delivery of my amazon.in buy

Address:	574327
Website:	www.delhivery.com

I had ordered for a product on amazon.in. This arrived unexpectedly early and i was not available on that particular day. I told the courier man the same. He said he would deliver it two days later that is monday, as per my request. But today i have been calling him multiple times, and each time he said it will arrive 'in a while". The while never came. And finally he stopped responding to my calls, i am utterly frustrated.
I tried calling up the amazon.in toll free number. Int he process i learnt it isnt actually toll free. And i never got connected with their costumer service. The same happened when i called up the '"delhivery" courier service.
This is the order id : ae[protected]
When i tracked online it says i have opted for self collect. I have not opted for it in reality.
