this is odd. I've had an email from Allianz saying I'm due a refund for event cancellation insurance, and as I was prevented from going to the event by Covid, I'm entitled to my money back.
It sounds like some sort of scam, but the email looks genuine (it's come via Ticketmaster), and what's more, I did have cancellation insurance to see Rod Stewart. But that was last December, and wasn't cancelled, and we went and had a great time.
Anyway, I don't have to do anything, £10 will just appear in my bank account. All rather unusual.
