Somehow my wife ended up getting several flight reservation charges going through on her credit card when she was trying pay for the flight through CheapFareGuru. Her bank cancelled her card and rejected all the charges. CheapFareGuru then kept trying and threatening to continue charging her a cancellation fee. It took 3 calls for her to get someone at CheapFareGuru to cancel the flight reservation. Still do not think this drama with CheapFareGuru is over.
