Franch Express Courier — courier [protected] delay and delivery man rude behavior

Hi, i would i like to raise my complain for my courier no. [protected]. Which was initiated
On 21st september 2019 in chennai, but still i didn't get my courier.
When i tired to track it, i got the contact number of the delivery person mr. Rasheed and i also observed that he had tried to call me yesterday but due to my work busy, i was not able to attend the call.
Today that is on 27th september i tried to reach him. He answered my concerns very rudely and also said that there is no service to deliver the courier to the address which have mentioned in courier and asked me collect the courier from the office. For this behavior i said i will raise complain then he threatened that he has local political influence.
If there is no service for the location then why is the courier being accepted and by the way the courier office which rasheed mention is just 15 minutes from my location and my really worried that franchexpress cannot deliver courier to a place which is just 15 minutes away from the office location.
