India Post — speed post not received and rude behavior of post master

Address:

Coimbatore, Tamil Nadu

I have not received my speed post yet. On 22nd of jan 2019, the sender communicated that they have sent me a speed post. Today the date is 29th of jan 2019. The post office is merely 3 km from our home. When tried contacting the saravanampatti post office number, the person behaved so rude and told me that the post man has the post but updated as houselocked, which is a false information. Also when i told them i have not received any call from post man (If in case they were unable to find the address, i thought they would call the number mentioned), the person from saravanampatti post office responded in rude manner, that they wont call at all. When i asked for the post man number, so that i can direct him to home, i was informed that he does not have a professional number and they cannot share the personal number. Also i was informed that to come to post office and collect the post at morning 8.
My concerns:
1) house locked is the false information
2) why dont they call to the specified number, so that communication is easier
3) the answers were not polite, they were rude in all possible ways.
4) sharing post man number makes the work simple, why cant they share it when asked
Above all the person hung up the call while talking which is too harsh and rude.
The post office is saravanampatti, and it is near sivanandha mills.
