flight Hub cheating client by confirm the insurance removed but charge the insurance fee Internet

On June 25th, 2015, I booked airtickets via Flighthubs, when the eticket email came through, I discovered the website add insurance in. I called flighthub immediately and request to remove the insurance. The person who picked up the phone call confrm with me that the insurance has been removed, I will receive refund within 2 to 6 business day, I ask if I will receive a confirmation email for this cancellation, they said no confirmation email, the insurance has been removed from the system, I will get refund. 2 weeks later, I did not receive the refund, and I called flighthub again, they adivse me that the cancellation of insurance did not go through in their system, I argued that I was confirmed the insurance has been removed, then they said there was no notes or record that I request remove insurance. I ask to speak to manager, they refuse to transfer my phone call, but put me on hold, I ask the address of their office, they refuse to tell me. They advise me that I have to pay for the insurance.
