Delhivery — Nykaa Product not delivered within Bangalore by delhivery

Delhivery delivers my product late everytime and now they have stopped delivery to my pincode 560068 and that too within Bangalore.
It shows non serviceable but other courier partner delivers all my parcels on time.
Without any reason or prior notice, they returned my parcel which i had already paid for.
Also nykaa team knowing that Delhivery has some issue in my area, deliberately handovers my already paid products to delhivery not once but four times.
And all shows the same status as Non serviceable.
Its too much of stress and harassment to customers
