Dont ever fall trap to online recharge offer on Sulekha where they are offering Rs.50 recharge for Rs.44 and Rs.20 recharge for Rs.16, and so on.
I recharged my Vodafone prepaid for Rs.100 and did not get any recharge and also Rs.99 was deducted from my bank account and nothing has been returned even after a week. I do not expect that it will come back.
So beware and do not use this horrible service. I got my lesson and vowed to use only authentic sites rather than cheap sites like Sulekha.
