NurseryLive — Order not delivered nor refund processed

My nursery live order NLV[protected] was placed on 27th April 2021
1 item In the order( money plant) is not delivered till date as of June 9 2021.
The blow horn delivery person Manikandan called Me and said that he cannot locate my address to deliver the item and that it would be returned back to nursery live.

Nursery live doesn't claim responsibility for my Undelivered order and says that they have asked the courier partner Blow horn to deliver as soon as possible. Which till today ( June 9 2021) is still Undelivered.

As I have waited for more than 50 days, I need Nursery live to claim responsibility for their delivery partner and refund me the due amount asap and follow ethical business practices.
