Expedia charged my credit card twice in July, each time nearly $500, for a single itinerary (r/t flights from Thailand to India).  It was clearly their mistake (the computer hiccuped?).  I sent the duplicate tickets back to them but the expected refund has not materialized.  I have a "case number" now but no other response other than form emails from the poorly named "Customer Service."    I fear I’ll never see that money again.  This is NOT a case of misunderstanding policy.  They charged me twice for the same tickets and have not offered either an explanation, an apology or a refund.  This program wants me to write more words but I think brevity is a virtue.  I think brevity is a virtue.
