Khama Anku Spiritual Physique ripped me off for $1395.00 Los Angeles, California

Khama Anku recruited me as a speaker in Atlanta for a weekend in October, 2012.  She told me I would have an hour to speak, and would be professionally videotaped.  The $1495 would cover hotel expenses, meals and the videotaping.  I heard nothing further, until I pressed her in September.  She emailed me that the event had been canceled and she was mailing me a check.  I never received it, and again, when pressed, I finally received a check for $100.00/ with a promise to send me the check for the rest.  It's been over 2 months and I haven't received any more money.  She does not respond to emails or calls.  I have contacted my credit card company to see what can be done.
