GMS Worldwide Express — Complaining about delivery.

Consignment no is[protected].
We have booked courier on 29.03.2021 from seethammadhara Visakhapatnam. The agent promised that it will be delivered by Wednesday or Thursday.. but still it is not delivered. The onlin tracking status is out sor delivery since two days.. we have called hyderabad delivery office regarding the same. We heard a lot of irresponsible answers from them. They said that to make a booking we will blame you that the item will be delivered in two or three days.. but we don't deliver them as said. Very irresponsible response from you.
