Hsbc
Hi
Been with them for years with no issues at all.
Been in and out of Hospital and using various devices and Wifi NHS addresses and others.
This has caused a few problems for me, especially when I have been very ill and drugged up.
It has triggered their security alerts.
All now resolved, a pain, but designed to keep a customer safe.
I did not ask for it, but they have now credited my account with £200 for my time and trouble.
I am very happy with that.
That really is customer service.
