Mongrol, Did you call and ask for the increase or did you ask for it on there website. I also have a 3000 CL with them, with 50% utilized with a 644 exp fico. ?
I called and asked.... told them*like I tell everyone* that I want to balance transfer credit cards ect over... ( I did pay my balance on my amex ... all 300 bucks of it... LOL) It took them about 2 hrs to approve... it wasn't the quick 5 minute approval that I usually get...
