Fraudulent charges to my cc account

[NewtonMP2100]

happened to me twice, 1st time with Citibank. . .I noticed many charges at "on the road" guess they were taking a trip. . .called up. . .that was over 15 years ago. . .

then recently there was a $200 charge to western union (also Citibank card for some reason) I noticed it because I check my credit card statements periodically online. . .called it in also. . . .
