Don't have calling credit on my Thai phone as I only use it for data so called the US number on Skype as it's free. I believe all the customer service numbers will port you through to a centralised call centre in any case. I had no problem getting through this morning but have struggled in the past few weeks, I was able to contact them through FB Messenger then though.
yeah, would have been nice if they'd let people know. Only happened to find out by chance the other day. Planes are definitely flying, I booked for mid-July earlier today after making sure today's flight had departed.
