No Feedback- cannot contact

CANNOT GET THROUGH TO THE CALL CENTRE FOR THE LAST 2 WEEKS! I work during the day and cannot spend 30 minutes or more a time on hold. They cancelled my flight and now I need to book a new flight with the "refund" and I cannot get through to them. The flight prices have gone up in the 2 weeks I have been trying. I am panicking big time!!!!!

Seriously need to re think their user experience in the way they are handling how to change flights!!!!!!!!
