Hey to all

)
My first post,what a great forum comunity!
Got couple of questions.
1. Is it better to actually call to apply for credit card,If I have extended fraud alert on the file?
2. I am AU on my brothers Chase credit card with high utilization.They are reporting 90% of the credit.Is it better to dispute the card with CB to get it removed( I don't think my bro will pay it off any time soon)
3. I have one charge off reported 5 years ago. No collections and about 39 INQ from 2 years ago.My EQ score is 658 ,TU and EX almost the same.Is it safe to apply for some good CC's?
Thank you
