Indian food delivery and ride-hailing companies like Zomato and Ola don’t appear to support it yet (and training their delivery folk), sadly. I wish they would though — it would make life much easier. Most delivery people I’ve spoken to are unaware of the feature.

Also Google Maps in India has quite a bit of variance from “ground truth” so the phenomenon OP describes (of delivery folk calling you up every. single. time) is very real.
