They’re still working through them slowly and refunding them one by one.
I had an email from the creation credit card team saying I had a balance on my card (one might recall these were closed in 2021 if you paid a certain building society).
Anyhow, I called up and BA had refunded £7.50 to them in January 2023. A search of the reference number 125-2XXX… in my inbox showed it was an FTV from April 2020 I’d long but forgotten about!
I’d call BA as they should / will most certainly get it moving.
