Some ppl calling from HSBC bank for opening a zero balance account; and they told me that they got number from tradeindia.com & alibaba.com etc. And have a tie-up with them. I have a number which is already DND but these guys / telecaller / sales ppl don't bother.
This foreign bank company is purchasing data base of importers-exporters from these CHEAP companies (tradeindia.com & alibaba.com).
These B2B companies don't have a strong privacy policy.

SHIT!
