No credit card required
Browse credit cards from a variety of issuers to see if there's a better card for you.
Many CC companies have Chat feature on their website while you're logged in look for a Chat Now" link. It opens a small browser window where you type messages back & fourth. I used Chat to to get a doubling for my Waalmart card CL, from $2500 to $5k.
Sometimes the chat feature is only available during regular operations hours. Depends on the bank/credit union.
