Here's some more info that I found

If you go to this website - http://bmobile.in/9591109014 - it traces cell numbers to their locations in India.

This is what the website gave me...
-----------------------------------------------------
Mobile Number: 9591109014 | Location:KARNATAKA | Operator:Airtel | Signaling:GSM

The operator/owner is probably in the following cities...
--------------------------------------------------------------------------------
Bangalore, Hubballi-Dharwad, Mysore, Gulbarga, Belgaum, Mangalore, Davanagere, Bellary, Tumakuru?(Tumkur), Bijapur, Shivamogga?(Shimoga), Raichur, Bidar, Hosapete

So the fact is, when I called 959-110-9014 - the person on the phone said he was calling from the Vodafone Helpdesk and from Mumbai (but the above website says Karnataka) - Hence, now I'm sure this is a scam. Be careful and spread the word please for the benefit of everybody else.

This could be a prank/scam/fraud as per Vodafone agents. I called them and confirmed. Also, when I spoke over the phone to the same number, the guy could not answer questions clearly and was fumbling. Clearly something funny going on. Don't give them any details please!!

i get missed calls from this number almost every night between 12 to 4 am.
