I got a call from 240-206-8441 as well and the person had a heavy accent with lots of noise in the background. What got me nervous was the fact that he asked for me directly. The caller also kept asking me to hurry up and choose if I wanted the money on a Visa/Master card or in my account.
I have gotten three calls from this number but i did not answer any of them, they didn't leave a message. I didn't apply for any credit cards... I don't know how they got my number
