Smart Fares Defends Airline's mixture of "incompetence," "lying to me," and "deception" won't refund my money San Diego California

I purchased a ticket in good faith and with good intention to fly out to Las Vegas where my daughter is going to be married in July.  I also took busness law in college and understand contracts, an airline ticket is not a 'tailor made suit' that no one else but the person purchasing the ticket can use.  A ticket can be sold to anyone.  Anyhow, when I called the airlines (Frontier) to inqure about chaning my return date, the representative gave me a one time fee of $100 to do that.  So, I agreed to it and gave her my credit card (American Express, that I have had for 39 years).  She told me that it was "declined."  I found that next-to-impossible to believe, so I gave her another one (that I have sizeable money available on); she told me that was declined as well).  So, I said "thank you for your time," being suspect of this transaction and then I called back in and talked to another representative that said that my transaction "wasn't declined," that the previous rep had put a claim or request in on my card for 3, $100 payments for the change fee! (1) Saying that it was declined, was flat out lie, (2) the second transaction was deceitful and an attempt to steal from me.  I immediately had to call both credit card companies and cancel my cards.  This transaction caused me much undue stress. 

Then I called Smart Fares yesterday and requested a refund.  The first person/lady that I talked to was nice, and wanted to set up a conference call with the airlines and I said "no."  Then she asked me if I'd like to speak to a supervisor and I said that I was willing to do this.  This is when the "good cop/bad cop game started" and I ended it and wrote to the State Attorney General about it.  The supervisor wanted to 'mix it up with me' telling me that I was confused and that I was complicating things.  The truth is, I wasn't confused and very articulately described what happend, and that I wanted my money back as I will not fly with Frontier.  A ticket, contract, issued under fraudulent circumstances, or, one that because that in the process of the transaction, is voidable!  Period.  These people all seem to be in cahoots with one another.  They defend each other, and as far as I am concerned, not honoring the truth is being an accomplice to devious, inept, and bordering fraudulent behavior.
