got this call twice today, didn't know whose number it was. just looked it up because I was curious. the number DOES NOT show up when my phone rings, the caller space is blank.
same as most people here reported: a couple of rings, then when i call back an automated system asks for a PIN. After reading the previous posts, my guess - the racist who blamed India is wrong, the anti-industrialist that blamed Citibank is wrong, the concerned but off-topic Julie is, well, off-topic. This may be an attempt to get PIN numbers. When you call back, they get information about your identity - phone number as a start. If you key in one of your PIN nunbers, they then have your PIN to "something". Putting together your personal information with your PIN (or multiple pins if you tried more than 1), they have much better odds of accessing your accounts.
