I was charged for a return ticket change, but Justfly never made the reservation. In order to return home I had to buy a new ticket. The message that they tried to reach me is strange as I have no voice messages. Since I am abroad, my phone number cannot be used. There is no functioning customer service. I tried to call repeatedly for hours, until they blocked my phone number. I also tried to chat with a customer service person online - waited for hours with no response.
