Delhivery — A product was returned without customer notice

Address: +91 80968 71109 , Nagarjun(station manager),Sri Rakesh Heights Kukatpally Hafeezpet

I was supposed to receive my delivery by 26th feb 2022 but due to delhivery's incompetence to meet the requirement due lack of delivery men and poor service the product was delayed. Though I approached the hub still they denied immediate delivery on spot and delayed it upto 8th March 2022 and on 9th March 2022 the product was returned to the merchant without customer's notice. Now I cannot get a refund either from the merchant due to his return policy conditions weren't met. On confronting the Delhivery station manager he neither accept fault at his side nor does he takes any kind of responsibility
