Blue Dart Express — rude and mannerless behaviour of the bluedart delivery boy

Please refer the conversation between my phone [protected] and your company phone [protected] on 15 oct 18. I was at office during the courier boy visit and when he called for delivery, i told him to just wait for 5 minutes till i reach my place. He rudely said he will not wait and after some persuasion he said he will take off as soon as 5th minute ends. When my friend reached the place 2-3 minutes later he was not there. After when i called him he teased me by saying he waited 10 minutes and 15 seconds. After that he asked me to come and wait at another place which was unknown to me and when i asked him explain the way he simply cut my call. I being a defence personnel certainly know the importance of time as that what matters to us, but seeing such heartless person at your helm it will be good that you deploy robots for delivery as they would be proper time complient. Because a human can adjust to some circumstances as in this case where he could not wait for another 2-3 minutes. His unwavering mannerless behaviour is another gem. Hope you look into this matter please.
