The Professional Couriers — Undelivered Package. Returned without Intimation

There was a package sent by IDBI Bank (Cheque Book). I received the SMS as below on 12th Apr 23.

DEAR CUSTOMER, YOUR IDBI BANK CHEQUE BOOK HAS BEEN DESPATCHED VIA PROFESSIONAL COURIER -AWB NO:VPL[protected] ON 12-APR-23.I[censored]NDELIVERED IN 7DAYS PLS CONTACT HOME BRANCH.

I had called customer care no[protected]th Apr 23; wherein she said it will reach in 2 days.

Since the first Message, I didnt receive any further messages or calls and this has now been returned is what i got to know after calling on the customer care no[protected].

1. How can the delivery person not call if they have not found the address?
2. If this location has not been covered, why wasn't I informed about this?

This cheque book was so important as the cancelled cheque had to be submitted by 23rd Apr. If the Despatched happened on 12th Apr 23, how long should it take to reach the destination?

Without even intimating, how can the package be returned? And how would the recipient know about it. Bank will say they don't have any info unless the package returns to them. How can a Courier service which is providing services since ages can fumble like this.

Can you please arrange for the delivery without any further delays. If not then I will have to further go ahead with a Complaint with Consumer Court.
