Help my mom

A someone , who use to be my best friend that I’m not going to put on blast , got my moms credit card information and sent herself over $500 . My mom doesn’t even have it like that to just forget about $500. The bank said the dispute could take a month , plus they don’t even know if she’s gonna get the money back . She has bills that need to be paid plus she works hard for that money !!!! My mom is literally so sweet and use to pay the girl who stole her money phone bill , sent her money when she asked etc . I really wouldn’t do this if I felt like my mom was going to be ok but she is hurt . And everyone who kno me knows I’m not the one so I’m not asking you to donate no $50 anything would help literally . And she don’t even know I’m doing this so if I could surprise her with the money I know she would be so grateful .
