Thanks. Yeah, I tried three times to make that Avios purchase with my Visa and it never even got to the stage where I can verify it via the App. So most likely they thought it was shady.

(Text messages don't reach me at the moment. I don't know why. My phone is using an Armenian network but for some reason, text messages don't go through. Well, maybe I get them when I reach Riga.)

I'll call them when I get home.
