Had a friend to call in once to ask for a CL increase with Chase. Instead of an increase, they reviewed her history (good payment history w/ high utilization) and told her they needed to decrease her limit and immediately closed the account because with the new decreased limit she was now over.

She tried to access immediately (by phone, I believe) and denied access since the account was shut down. The rep. hung up real quick after closing her account.

Sounds strange for someone with high credit scores. But this was several years ago when the economy was plummeting.

Note: she also had the change of income (decreasing) for that year as well.
