I have called TravelUp for 3 days straight with no answer. All of their phone numbers are showing as the lines are busy. Yesterday i started calling at 9am and called 5 times and hour until 6pm with not a single attempt connecting. I have also emailed them 3 times with no response. They say they will respond within 48hours but this is not the case. I need to cancel the flight and get a refund but i cannot get a single response from the agent through any medium This meant that i cannot get a refund or cancel my flight and the airline will not speak to me about a booking as it is with an agent.
