Boat — Neckband ordered

Boat Order ID - 1864764
Bluedart prder ID - [protected]
Ordered neckband from Boat on 14th April and delivery date was showing 17th April.
Its 28th of april amd still i jave not got the parcel. I have called Bluedart multiple times since 18th April but they are just saying we will deliver in next two days but 10days have passed and still no sign of delivery. Courier company is not calling me to deliver or if they are facing problem regarding address then they shoul call atleast i can go and pickup myself but they are not doing anything. ( I have Provided two phone numbers). But they dont call.
Boat customer executive also i tried multiple times but they never did anything.
I have asked them to cancel or refund my order but they say they cant do anything.
My money is lost and no sign of package.
Really frustated with this much carelessness and informal way of both Boat and Bluedart.
