Like the title says I switched my account to Monzo and it fully switched on Tuesday. On the same tuesday, I paid for an Uber which was still linked to my old bank. The balance on this bank is now showing -£9 - why hasn’t it just been taken out of my Monzo balance which has funds? I thought my Santander account had been closed? I’ve already tried “paying” my old account using the details and obviously the money just redirects and pays myself into Monzo.
