Bigbasket.com — Complaining about delivery

Gudavalli,cherukupalli md,bhapatla dist

We had done shopping for the RS.1200 the delivery boy is saying us to take the delivery from the office in gullapalli. He is saying that if the products are above the1500 rs he will give the door delivery else we have to collect from office.or we have to give the extra charge for him of 50rs to get products delivered.
But the site is showing free delivery.
It is the 2nd time we are facing the same issue.
