Sounds like he was describing the Oasis program. Pay your delinquent balance in full, get a new Optima card with a CL equal to half the amount you paid along with removal of all derog information from your credit reports and backdating of the new account to the open date of the old one.
Oh, something I probably did not mention in my first post and something that may have some significance. The first phone contact with CA the gentleman (and I use that word losely) told me that if I paid the account in full that Amex would reopen the account and give me a credit line of $8000, isn't that generous of them to offer to do that?", etc. That conversation was so confusing to me because I didn't know who he was or why he was calling, and I don't remember a lot of what he said to me.
