myflightsearch.comは安全ですか？

Ordered a ticket through this site. Got email confirming reservation followed not long thereafter by an email saying the flight itself had been cancelled. Call Myflightsearch to cancel their reservation. They said they cancelled it. Nevertheless, the charge appeared on my credit card. When I contested the charge with the credit card company the credit card company replied to me that Myflightsearch said they delivered their services, namely a flight reservation. Would strongly recommend not using Myflightsearch. Additional note: When I called the airline itself, the flight had *not* been cancelled and they never had a reservation for me through Myflightsearch.
