India Post — misbehaviour and threatening by post office staff

Address:

North 24 Parganas, West Bengal, 743271

Sir,
On 30th june 2018, i went to hijalpukuria sub post office, habra, north 24 parganas, west bengal (Pin - 743271). I reached there before 12 pm to do a speed post. When i went there the staff was not at the counter. When he came back he refused to do my work saying that - i did not attend there before 12 pm. I requested him to do the speed-post. But he said - ' do anything, go anywhere, i will not do your work.' but he did the work of a man who came after me. Astonished with the behaviour i asked the post master to resolve my problem. But as soon as i asked his help, all the staffs of the post - office started misbehaving with me. All of them started insulted me in a very rude and wild manner. After requesting for half an hour, they said to come after 4 to 5 hours. Isn't we have the value of time? Isn't they think we are humans. The languages what they used are very agressive and wild. Totally angry and disappointed with the incident.
Please take this complaint as serious. It has now become a normal thing, that customers are misbehaved by the staffs. I protested. And needs your help.
