Overnite Express — worst courier service - overnite express

I am facing serious problem with overnite express services.

I couriered a document on 10th of may from mysuru to indiafilings.com, chennai.

Docket no. [protected]

Problem:
* courier was booked on 14th may in mysuru. (I dont know why there was a delay of 5 days in booking the package)
* online its showing bangalore as destination, but the destination is chennai
* even if my package is delivered by 17 may, it means overnite express takes 7 days to deliver a package from mysuru to chennai (470kms).

When will my courier be delivered to chennai destination address???

I spoke to you mysuru regional office lead, but to my surprise he simply said that offices were closed and so the delay and disconnected my call in between conversation. Which i believe is just an excuse because:
I booked another parcel on 10th may with speed post (India post), which was received in chennai on 15th may. (Much faster than overnite express)
I know you won't even care to respond to my query. So you would leave me no option to go ahead and post my agony and queries all over social media.
