Thanks for that link, very helpful. I had a ticket booked on the 3rd April departing from the EU which LATAM cancelled last night.
I submitted a refund request and to my surprise it confirmed the correct £ amount I was due back and said it would go on to my CC (within 15 BD, although said it could take longer due to the current situation).
It now says "In payment process".
Side note: I was unable to add my bank account info as 'back up' to my original cc info, as for the UK it lists no banks on the drop down and won't let you continue with this blank...
