I'm sure the OP (if they are even still bothering with this thread) is very pleased about the star collection box, since it helps them so very much. Yes yes, they should have posted in a different, preexisting thread, but they posted in pain, after all, so I will respond.
I would say that the first thing to do is take a deep breath. No need to list all your troubles like the ten sons of Haman.
Then, assess the actual damage. If you always paid on time, as you said, hopefully there will not be a huge financial impact to you in the short term by having your accounts closed. There may be a few automated payments they set up that they will have to reroute to other cards or cancel. Hopefully you did not keep ALL of your money in Chase, and any balances you do have with Chase they will eventually refund you. I don't know about the impact to your credit report from having a bank shut you down, but you should look into that. It might be worthwhile for you to get some honest, paid help to work on your credit report, but others on the forums can certainly advise you about that better than I can.
Other than that, the damage is really the lucrative future potential earnings from opening and MSing Chase cards. This potential is significant, so you should definitely pursue a clear understanding from Chase as to what happened, and what they think about your activities. Go to branches, call, HUCA, HUCA again, write letters, do what you have to do to get a clear answer. This will take time and effort on your part. Be patient, and above all be professional. Go to branches calmly and dressed formally. Be clear and articulate in all of your communications. Emphasize your longstanding relationship with them (if you have one) and that you are a gainfully employed person (if you are one) with firm roots in your community, own a home, etc. (if you do). Your persistent contact with them, verifying your identity whenever asked, etc. - rather than running and hiding - and patiently making these points demonstrate that you are not laundering drug money or doing other actually nefarious activities (assuming you aren't).
If the closures really are permanent, and the damage is irreversible, it deserves a moment of silence. Maybe even a week of shiva is appropriate - I'm only half joking, it's Chase, after all!
Many of us have been shut down from something we've enjoyed using profitably and it definitely hurts. It sounds like a cliche, but with a little time and perspective, you will recover, trust me. If you stay in the game, you'll hopefully be a little wiser and more careful. If you get out, and find a different hobby, there is no shame in that at all.
In this game, all good things tend to come crashing to a halt eventually, be it by closure, devaluation, merger, publicity, rule change, uncooperative employees, etc. etc. Know the risks going in, reassess the risks periodically, don't risk more than you can afford, enjoy the ride while it lasts... and get out and live life outside of the hobby to put it all in perspective.
