I've had the same problem with Santander. I can get as far as having them send me the access code to open internet banking but they send it to my house 'phone which does not take the code rather than sending it to my mobile 'phone, which would receive a texted number code. When I rang their Madrid office I was told that I could only change the 'phone number that they call by doing so at the branch in Spain, even though they have details of both my home and mobile 'phones.. It's like complete obstructiveness for so called security reasons, perhaps because the UK has left the EU.
