Hey, I'd say go with BookMyForex. I've sent money to my sister abroad using their platform a bunch of times, and it's been a pretty smooth experience. What's cool is that they're all about keeping your cash safe. They partner with legit banks in India, so your money is in good hands.
I even chatted with their customer support, and they assured me they were on top of their game. Checked online too, and people seem to like the platform - they got a solid rating on Trustpilot. So, in my opinion, you can trust BookMyForex.
