No, they're overloaded with calls, just like all the other airlines seem to be.
We’re experiencing high volume for our phone, email and social media support and you may experience a busy signal when trying to call us. Thank you for your patience. Rather than wait on-hold with our call centre, try finding support here: https://ms.spr.ly/6015n15G7
I can certainly understand and even sympathise with being busy, but to prevent access to "travel bank" funds (which they are holding onto rather than returning as refunds), attempt to get customers to pay for flights by other means, rather than with the travel bank funds, and then send automated messages with 48 hour wait times for a call to be answered seems like a more troubled situation than just being overloaded. They're not even issuing any general statements that they would suggest they're even acknowledging the current situation. It's a very difficult situation to leave their customers in and is very nervous-making.
