I am trying to cash in a savings certificate. The NS&I website seems to wo rk; I can log in, select the certificate, click to cash it and I then type into my phone the 4 digit code that NS&I put on the screen and then call me for confirmation. The phone says the cod eis correct and that the screen will change shortly. But the screen remains unchanged. When I check later the certificate shows as 'no transactions'.
Has anyone else experienced this? It's been like it for several days.
