Ecom Express — Shipment not delivered on time

I put ordered for vestige product on there web site on 27 sep 2020 after two days I received msg from them that my order will delivered by Ecom express along AWB number to track my order on Ecom express web site today it's 20oct 2020 but still I didn't recieve my shimpment and now on Eco express website it's showing that my shipment is RTO locked. Ecom express totally fraud and they provide very poor service also there customer care services also not give satisfactory reply. I just want my shipment delivered asap. And heavy penalty on Ecom express so other people won't suffer in future.
