Afternoon - I did. My flight was due to be Wednesday 25th, but was cancelled last Sunday night. The website or app don't support requesting a full refund, so I called the call centre on Monday morning - dialled at 8am ready for them opening, and a mere 95 minutes later was connected. Full refund confirmed, and money was back onto my credit card by Thursday. Given everything else going on I'm really pleased with that.

Good luck!
