India Post — Non deliverance of registered post

Address:

Jaipur, Rajasthan, 302015

Dear sir/ ma'am,
This is to bring to your attention that we were to receive a registered post by Income tax department and as checked the status of the post said that the respective post office which is Dantli, 303012 have received the post on 24th Sep, 2016 and we have never been informed or the post man has not even come to the given address till date. We figured out the status and checked at Dantli post office on 14th October 2016 only to find out that the post office is been closed long back. We figured out the mobile number of the post man who was looking at this post office, and we were informed that someone else is handling this area now! We spoke to that post man (the new one) on 14th and he said he lol chk and get back on the post! He kept giving reasons for not delivering and in spite of going to the post office (Kanota) under which Dantli area comes. On 17th he promised to deliver the post when we went to the main post office of Kanota. That again did not happen and there is no post office at Dantli where we can go and collect the post. We are stuck up here as we cannot go and pick it from the post office and this guy isn't delivering the post.
This post includes the tax refunds and these cheques have a limited time limit and after that these cheques are expired.
Kindly help us out with this issue.
The post is of jagatpura area, under Dantli post office- Kanota post office, head office- Jaipur
city 302015.
