DTDC Courier & Cargo — DTDC has delivered a product to a wrong address

Address:

No.88, 167, Perambur Barracks Rd, near bhuhari hotel, Vepery, Purasaiwakkam, Chennai, Tamil Nadu 600007

I placed an order with ibuychemicla, chennai for n-heptane on 8th Jan 2024 and the order IBCINV0007X47886. The order shows details of the order with the address of the receiver. The order also gives the tracking I'd of the courier as 7D3238332.
On checking with DTDC website, the order has been delivered to someone in Chennai. On sending a mail on 13th Jan, DTDC is still processing the ticket. When contacted ibuychemiclas, they are passing the buck on DTDC. DTDC and ibuychemiclas should send 5he item immediately and pay for the damages.
