Ah, now here's the problem. The bank is quite insistent that these things are updated online. So we go into the account details, change the phone number and they send a code to the new number, which doesn't arrive! When I had an online chat with the bank, they said it must be our network provider blocking the number. So I guess at the moment the only alternative is to sit on the landline for hours waiting for them to answer so we can discuss in person. I'll try that and if the codes still don't arrive then something is blocking the number. Thanks for coming back to me. I'll let you know how we get on!
