Does EK have a dedicated phone number for first class passengers? If so, where to find it or could you be so kind to DM me?

My dad is trying to change his flights after a couple of cancellations / confirmed future cancellations but he claims he can't get through to an agent. It's possible he's being the entitled boomer here and giving up after 10 minutes.. can't force him. He's in WLG and I'm in YYC. (I did confirm their booking online and it's F, online rebooking doesn't work). Just wanted to double check if they have a priority line available?
