India Post — rude behaviour of counter employee

Address:

Madurai, Madurai, Tamil Nadu, 625001

Dear sir
On 14.7.2019 I went to Madurai India post
SP Madurai RMS booking counter for sending a speed post with acknowledgement card. on that time (7.30am) there was no person in the counter. (That counter is 24x7 )
I asked for acknowledgement card at the office. They gave that. I filled it and I was waiting for 20 mins. He finally came to the counter at 7.50am . I have stapled the acknowledgement card on the speed post and gave that on the counter. The counter employee said like he cant accept it for sending because it was stapled. Then I argued that I have sent a lots of speed post with acknowledgement card stapled. But he refused to send it with acknowledgement card which was stapled. And He throwed my speed post letter and said I wont send your speed post take it and get lost. I got anger and asked him for reason. He said me to remove the acknowledgement card. It was a important post that should be sent with acknowledgement card because of him I sent it without the acknowledgement card. He is so rude.
