I have sympathy with you if the story is true but that is all I have and I cannot help because there are people with new stories every day and you don't know who is actually needy and who just wants to gamble with the funds. I suggest finding some work rather than begging because it won't work.

So you don't have money to eat but you are returning 20% within 7 days, does this make sense at all? At least not me unless you have a payment coming from somewhere which you haven't mentioned.

If you are begging for money and actually need it, you shouldn't be promising a repayment because let's be honest if you are under such circumstances you cannot afford to pay it back.
