SD30 just used my credit card to pay her $270 past-due cellphone bill. I put her on my card last month in an emergency when she had a car accident & needed a credit card to rent a car. DH made it clear to her that the card was for that & emergencies only & she was to call him before using it. I have alerts set on the card so I know immediately when it is used. Needless to say, she didn't call us & a cellphone bill is hardly an emergency. I am furious!
