Ask HN: Twitter account hacked (via mobile # hacked first), help?

Hi HN, today my t-mobile account has been hacked (due to a very poor security practice at T-mobile... long story short, someone changed my SIM card without my consent, and without inputing my PIN), and consequently my Twitter account has been hacked too.

I tried for hours but didn't find any way to contact Twitter's support directly, or to restore my account (email has been changed, of course).

Anybody has a friend at Twitter? Or, do you know what to do in these cases?

Thanks in advance for your help.

p.s. It seems that T-mobile cannot be sued for damage at all, because of the arbitration agreement made possible by Scalia.

I don't care about getting money for the disruption; but without significant monetary incentives, I fear that T-mobile won't do a thing to fix their security issues.
