Not enough data
We couldn't find much for "how to apply for refund in gst for export with payment of tax".
Google doesn't have enough autocomplete data on this phrase — probably means people aren't searching for it in this exact form yet. Try a product, place, or topic people actually look up.
This isn't an error — autocomplete reflects what real people type. If a query is brand new, very niche, or gibberish, search engines don't suggest it. That's honest data, not a bug.
