it is safe until the system is hacked. do i think they will pull money from my account without my authorization, NO !!

I used to use Muncha for a while until they closed their site. They used to deliver money to my home and send me the proof of delivery with my mom's picture. I used Prabhu a couple times thereafter - they are really fucked up in terms of customer service..once the money wasn't delivered for 2 weeks and I was not notified of the delivery another time. Since then, I started using ThamelRemit. They haven't failed me! The friendly bhai (forgot his name) calls me to ask me how I am doing every now and then. I call him to ask the exchange rate etc and he picks up the phone in one ring! I have even trusted them with my bank account number so they deduct the money from my bank whenever I need to send money home.
