were you told the account closure is due to 6 months inactivity?
Have you talked to the phone rep about re-instate the account? Since Ink Bold carries a $95 annual fee, I find it hard to believe Chase would close it due to inactivity. Chase would happily bill you the $95 year after year.
I know our PC cards are not used for over a year with the only activity being the annual fee. Nothing happens to them.
