I had booked on bigbasket for home delivery of grocery items in chennai during the rains, because of the rains.
They confirmed some time for delivery when called they said they could not reach me and thus cancelled, the next day they said they do not have any deliveries thus will deliver on Sunday morning at 7:00 - 9:30 am.
I call on sunday morning they said they will deliver within 4 pm but by 9.25 am I get a cancellation. I call them again they say they will deliver positively by Tuesday, after which they neither called, nor delivered.
