Answered the call by mistake - some idiot in brok-en en-gleesh wanted to know about our FEDEX account. I gave him a bogus number and said that we had top secret clearance to ship anywhere in the world for to all state governments. Told him that the number he should call is (a bogus number starting with 555) to find out more about our FEDEX account. They have not called back since -

This is an Indian call center. They were making calls for Ziff Davis to promote some kind of software.

I just got two calls in a row, but didn't answer.  Called back to hear, "the magic jack customer you're trying to reach is not available..."

Claimed to be from Larsen & Toubro, or  LNT.  I have received numerous calls from this number. Every time, they claim to be from a different company. I've heard FedEx, Ziff Davis, Tech Research Assets, LSI, Johnson Control, US Bank, Citibank, Bank of America, UPS, NBC, and Coca Cola Company (ha ha!)  They ask for various employees and want me to confirm titles, e-mails and addresses.  They never get past me!  I'm on to them!  
Beware!  These people are relentless and obviously up to NO good!

They've called now 2 times, I keep asking what the purpose of the call is and they say it's personal. I tell them I can't put the call through because you seem to be calling from a call center, then they get rude.
