One other thing, when the charge shows up on your credit card statement, call the card company and dispute the charge and they should reverse it. Good luck!
Found a call from this number in my "caller list" while double checking the number on another unfamiliar number - unknown call that just came in so I could research that call (BTW - for those interested that call that I'm wanting to research was Kansas City MO 816-654-6450; left no message, no idea who it was)
No idea who this 202 number is. Caller ID said: NMG INV DEPT
Whoever they are, they left no message & will be blocked along w/the other number I mentioned here.
