Who called from 9197938599

some lady with a heavy indian accent told me I was entered into some type of visa/mastercard sweepstakes and wanted to verify information, she also had my address which was creepy...I ended up hanging up. This is the 3rd time in two days I have been called by this number, first time I have answered it.

Called me twice today 6:53 PM and 12:15 PM. No Message, They must of got tired of calling girls now they are calling boys.:)

This number has called my bf 3 times today hang up everytime he answers and is non working nmber when he calls it back

called me just a few mins ago at 9:10 PM. very weird.

I got a call like around 5 or 6 not sure. They said the same thing to me about $2500, winning a mustang, or a trip to i don't remember where.  They said there some sweepstakes place.

But when i called back i get a message saying "The number you dialed is not a working number"

They did ask for info but didn't give out SS when they asked.

Not sure if its for real cause I did fill out some survey when i was downloading an application.
What can you do??
