You filed a BBB complained almost 2 years later? Or was the complaint filed with the BBB filed a while back? And you are only now thinking of retaining a lawyer?

If you've let all this time elapse from escalating the issue, why is that? I certainly would have been more aggressive if I had a similar experience. Years ago, my wife had 250k MR clawed back from AMEX in a situation I thought was totally unfair and unjust. I fought AMEX and threatened litigation, was able to settle for return of her points, return of her AF, able to redeem (transfer) all her MR (600k+ at that time), in exchange for then closing the account. She was blacklisted from AMEX for 7ish years (this was agreed to in advance, in writing) which I didnt care anymore since she had pretty much had every AMEX card/bonus of interest to us, and we also had moved onto Chase for primary relationship at that time and I retained my Biz Plats, etc. But certainly, I didnt allow any significant time to go by before threats of escalation, etc.
