Delhivery / Ssn Logistics — undelivered shipment

I ordered a refrigerator from flipkart.
On oct 5th, i get a text from flipkart that the package will be delivered on that day..
Next i get a message from delhivery that they cannot reach me.
So i immediately called back. The guy lied he couldn’t reach my number (But i could call him back on the same)
He didn’t identified himself but asked me my address.
After i said the address he said they do not have a pickup van for delivering the refrigerator. So it may be delayed and come in the evening or the next day.
When it didn’t came till 18:30, i called back and asked if it was still going to be delivered on. They said it wasn’t picked up for delivery and so it will only be delivered tomorrow (6th oct).
Then i get a text “customer rescheduled the delivery”
Next day, i called them again and they said it will be delivered between 15:00-16:00
When the package didn’t arrive till 17:30, i called them again but bo one would pick up the phone.
I tried a few times but they won’t pick up my phone.
On 7th oct, i sent an email to customer. [protected]@delhivery.com explaining the issue. I got a response on oct 8th from vipin assuring me that it will be delivered within 24 hours.
But there was no contact or attempt to deliver.
So i replied to vipin on 10th oct, after double the time they assured me and yet there is no response from delhivery customer care or local delivery people.
