I use santander online banking, but the access of my online banking gets block for no reason all the time if I logon again and again they block my access even for the big and small transactions they block the access just because they doubt my transaction for security reason they block it without any prior notice. I have to call the bank all the time to unblock my online access...... there will be important transactions to do and during that they block the access due to which i had to face so many losses in my business life, it's such a time waste doing all these calls and all to get back the access....Munzo bank is most easier and best......
