Many years ago, something like 25 or 30, I opened a non-resident's current account and a non-resident's deposit account with what was then Banco Popular Espanol. All went well and I operated the accounts quite happily until quite recently.
A few months ago, Banco Popular was acquired by Santander and, even then, I was able to operate the accounts via online banking without problems.
Then, with no notice or explanation, Santander changed my access codes so that I can no longer access the accounts - not even to establish my balance.
Santander seems to have adopted a xenophobic policy because they no longer have foreign languages available on their website, but they appear to have withdrawn the English language facility on their telephone helpline. The only advice I can get from them is to call into one of their offices which, in the current climate I cannot do.
Thus, I am left unable to gain access to my accounts.
Can anybody suggest, please, how I can resolve the situation?
