St Courier — My parcel returned without my knowledge

Address:

Konganapuram

I have ordered a product in a ecom company on 23.03.2021 they sent it through St couriers and it reached my local office on 24.03.2012 and it out for delivery too but the delivery person didn't deliver it to address and not even informed me about delivery over phone call. They simply returned the parcel still I'm waiting for my parcel and I'm questioning that ecom company for the delay this is too much annoying and very poor service kindly look into this issue make a solution for this. Thank you.
