DTDC Courier & Cargo — undelivered imp doc and forged the contents in return

Address:

Krishna, Andhra Pradesh, 520002

We have booked one important and confidential letter from United Bank of India with consignment No. H82291213 on 16.07.2018 from DTDC Vijayawada Ramamandiram Branch with VF 564 phone number[protected].
On 17.07.2018 in online tracking it was showing at Bala Nagar, Hyderabad. But even on 18.07.2018 the consignment was not delivered. On 19.07.2018 we have called on[protected] which was mentioned in the receipt. The representative stated that it has reached Secunderabad for unknown reason and they will send a communication to the concerned to deliver by evening. As it was not delivered on 19.07.2018, called again on same number on 20.07.2018 in the morning around 10.15AM. This time the representative stated that it is at Chanda Nagar and will be reached by evening. We once again called on same number and Mrs Bharathi who was initially stated her name as Sarathi, who booked the consignment received the consignment informed that it has been rejected as the address is incorrect/not registered. We have lodged a complaint on same to customercare of DTDC for explanation and requested the local office not to return the consignment till the reason is known. But for surprise, today on 21.07.2018 the consignment was delivered in our office with hand written status " Phone Number Wrong" by inserting one additional number "1" between 10 digit phone number on the cover.
We request your good office to intervene and take serious action for
1. Non delivery of the goods within time.
2. Returning without a valid non-delivery codes and/or attempts
3. Forging/tampering the contents of the letter/phone number and misleading by altering the details for the evidence of return reason.
4. Failing to deliver even after continuous follow up from this office.
